The Tackles in this draft are good, but they're not fungible/interchangable, each has a rather distinct set of strengths and weaknesses. The OT position is one of the most difficult, most complex, and most thinking-intensive positions in football, it really is.
The vast majority of LT's are asked to dominate the very best pass rushers in the NFL. One mistake, mental lapse, poor technique, or athletic shortcomming can result in a devestating play like a hurry, sack, tipped pass, fumble, or injury to your QB. Even the fear of a backside hit makes many QB's--including Brady--underperform because they've got fear of that hit in the back of their minds and their vision is constantly distracted as they try to watch the rush out of the corner of their eyes; when they should be watching the receivers and coverages and trusting their linemen and "feel" of the pass rush. For these reasons, LT's are extremely well paid, never appear in FA, and are tremendously scouted.
But, the reality is that the NFL scouts have really nailed the scouting of T's and especially the LT's. It is now one of the lowest bust-potential positions in football, which is quite impressive. Sure, ultimately you can't get inside a person's head and never know what's really going on with a prospect or how he will handle the new lifestyle, etc. But there are less Robert Gallery's than there are Ryan Leaf's, Yatil Green's, Aundray Bruce's, etc.
Not everyone agrees, but here's my assessment of the potential LT's:
Clady: Best pass pro and classing LT, this kid has growth potential and already possesses the fluidity, skills and ability to be a force guarding his QB's blind side. If Cam were still coach he'd be my 1st choice LT because he's a wall in the passing game. His run blocking isn't special though. He doesn't have truly elite power to repeatedly blow away his man, but he has enough skill to do a decent job.
Williams: This kid has the dreaded "P" disease .... Potential. He has the athletic skill to potentially be the best in the class, but he's very raw. He would absolutely work for a team like the Dolphins where we have 2-3 years to let him develop into a monster. He can be a great pass blocker and great run blocker, Bingo! ... except that he's not. Life with him at LT would be like taking a shower while someone keeps flushing the toilet, annoyingly and painfully the water runs hot-cold-hot-cold-hot. We'd eat up the clock and move the chains then he'd miss a block and we'd have 3rd and long and not convert. Our QB would have all kinds of time one play, then get hit by a bus as Williams misses a block. In time he'd be exceptional, but for a year or two he'd be murder on us as he kinda learns the ropes.
Otah: I like this guy a lot, but he's still rough around the edges too. IMHO, he doesn't have as much pass pro potential as Williams, but he's got pro-bowl potential as both a pass pro and run blocker. But at the moment, he's just not the finished article and he's going to take his lumps as a rookie. Again, good fit for the Dolphins really.
Unfortunately, Clady isn't the run blocker we need under Parcells, so scratch him. Williams and Otah will both be taken in the 1st round in the 7-21 spots I think, where we're highly unlikely to be drafting.
Long: While everybody and their brother is willing to let Williams and Otah develop, nobody seems to be OK with letting Jake Long refine his pass pro techniques. I think he's the obvious Parcells pick and is going to be a great player, perennial pro-bowler, potential all-pro for many years. This bit about him not being able to handle speed rushers is far overblown IMHO. The kid from Purdue beat Joe Thomas but Thomas did just fine in the NFL, and that year Long was better against the same competition in Long's first season as a LT. Now Long has even more experience, and pitched a shutout except for 1 play against one of this year's most feared pass rushers, Vernon Gholston. AND, Long has nice long arms that will really help him compensate for his lateral quickness. Long will be a good LT in pass pro, people are just being nitpicky, this kid is the real deal. Run blocking, well I've heard differing opinions so I'll preface mine by saying IMHO Jake Long is by far the most dominant run blocker at any position in this draft and will be one of the top 2-3 run blockers at LT in the NFL for years to come. He is not only worthy of the #1 overall pick, he's the best LT for a Parcells system that has come along in a long long time (pun intended).
As for the 2nd rounders, let's not kid ourselves, there's a huge drop off.
Albert: I'm a UVa fan and have watched Albert with eager eyes since he enrolled. He was billed as the best OL guy of his class by at least 1 service. He came in to replace Ferguson, the starting LT of the Jets. Well, Ferguson stayed around longer than anticipated, and the Cavaliers were fortunate enough to also recruit Eugene Monroe, also one of the top 5 OL prospects of his year. When the dust settled, Albert--who came late to the position--played LG but he could have easily been a LT. Those of us--and I'm one of the first on any of these boards that I saw say it--that believe he can play LT in the pros recognize that he's going to have a steep learning curve and is best starting out as a G. He's well taught, but relatively inexperienced, and the jump to the NFL is a big one. Shifting to LT in and of itself will require time, so I wouldn't do both to him at the same time.
Baker: I'm actually higher on him than most people are. I think he can play LT and it's his best position and he is going to surprise a lot of people. His measurables are mediocre and he's overshadowed by the sheer quantity of talent at this position this draft, but he is a real player and he'll be a satisfactory LT in the NFL. The real reason he's slipping to a 2nd rounder is because of his injuries, not his lack of power, lack of speed, or any of these other things being posted. This kid can play ... but he's not a power player type that Parcells requires, so it's not going to be with the Dolphins unless we bite the bullet and have no other LT candidates to choose in round 2 (and we pass on Jake Long in round 1).
Nicks: I have a lot of doubts about him, one of them is his ability to play LT.
Everyone else: Nope, they can't play LT at an acceptable level in the NFL. Round 1 is absolutely loaded with LT's, but after that, you've got long odds to find one.
This draft is strong at Tackle, it's got a lot of exceptional LT prospects at the top, many solid RT prospects (Cherilius), and a good amount (McGlynn, Benedict) of tackles that I think will make good guards in this league.
But the LT debate is kinda silly IMHO. Unless we can trade out of the top pick, and/or trade up into the 1st round, we're not going to get any of those LT prospects except Long (#1) or hope that Baker is there in the 2nd round. Otherwise, we're looking at Carey playing LT again ... and I for one was surprised that he did an OK job, not great, but better than I expected. Still, I'd like Jake Long, who would be a massive improvement in both the pass and run game.
