Grabbing Rohan Davey would make sense. Saban has experience with him, and his big arm and physical prowess are characteristics that Scott Linehan seems to require in his system, if his tenure in Minnesota is to be taken into account. Of the guys who've had success in Minnesota, they've all been very strong-armed, Frerotte included.
One thing to note though, I read in an article that the whole "wolves not sheep or sheep dogs" thing came about after Saban admitted that his LSU team rose and fell with Rohan Davey becoming their natural leader. Saban didn't want to stake his career on one guy like that again. He may or may not, therefore, have an aversion to Davey. Then again, he may feel that Davey is perfect for this offense and he just needs to make sure that he surrounds him with wolves instead of sheep so that they won't rise or fall depending on whether Davey's having a good or bad day...
I'm tired about all the whining about grabbing "another mediocre quarterback" In this league, that's just about the only way you can GET a good quarterback, is to find a mediocre one and let him surprise you. We used our #2 pick on a runningback, because there was no QB available even remotely close to being worth the #2 pick. And, we'll probably not pick that high again. Get over it. You say Drew Brees, and I say he's neither fit for Linehan's system, nor is he the premium name everyone claims. Nine times out of ten, if you're acquiring a "premium" quarterback, you're paying a premium price for a guy who doesn't turn out to be as "premium" as you hoped. In 2001, the "premium" quarterbacks that were available were Brad Johnson, Elvis Grbac, and Trent Green. Grbac and Johnson were free agents and got big contracts that neither turned out to be worth. Johnson had some success in 2002, when they won the Super Bowl, but he was helped by a defense that rivaled the Baltimore defense of 2000. He sucked the first year he got to Tampa, he sucked in 2003, and he sucked in 2004. So the Bucs paid like $25 million for one good year of quarterback play. And Elvis Grbac, whoa boy I don't think I need to say anything about him. Meanwhile Trent Green has done very well, but guess what KC paid a first round pick to get him, and that was only because Vermeil had coached him before so he knew exactly what he was getting. Nine times out of ten you simply end up overpaying when you're trying to acquire a "premium" quarterback, because if the dude really was "premium" then the team he's coming from wouldn't be letting him go. In the salary cap era, "overpaying" is the biggest sin in personnel management, be that overpaying draft picks (see: Williams, Ricky) or overpaying salary cap dollars (see: Grbac, Elvis). The only time the premium price thing seems to work is when the coach involved has a good beat on the guy he's acquiring because he's coached him before (Hasselbeck and Green).
I guess if we get another high first round pick, we can do that roll of the dice thing where we draft a top 10 QB and hope he pans out, but until then...we cycle "mediocre" guys until we find the right one in the right situation. Rohan Davey would be perfect for that.
