I live in TN, am a dolphin fan, and have watched tons of VY games over the course of his career (almost all)..it bothers me to see people trashing him without having any clue of what went down in TN, and without having watched him play at all. Newsflash: ESPN's goal is entertainment, drama, getting viewers. As had been proven numerous times, you should not take their word for fact. If you really think they follow the small-market Titans carefully, you're crazy..
Here's the VY situation, and why as a Dolphin fan, I think he's by far and away the best option for us right now.
First, the "mental problems": Vince had a problem with ONE person in TN--Jeff Fisher. His teammates liked him (CJ/Britt especially wanted him back--Britt even got fined for writing "10" on his towel in a game after the ****storm), and his other coaches like him (old QB coach wanted Minny to bring him in). As any real Titan fan will tell you, the situation was far from a one-sided problem. Fisher never wanted Vince as the starter, and fought to undermine Vince at every possible moment. Amazingly, Skip Bayless is one of the only ESPN figure-heads that I have ever seen mention/understand this. Actually, you guys should be familiar with this situation--remember the TN-MIA game, where Collins started bc Vince was "hurt", but then Vince came in and ran around looking completely healthy? Well, immediately afterwards, Vince immediately got criticized by fans and ESPN for "not showing heart and sucking up his injury" to play. Next game, Vince gets his thumb injury, wants to go back in and Fisher won't let him. Titans lose in OT. Later it comes out that Vince begged to play the MIA game and finish the Wash game, but Fisher wouldn't let him. These are only the 2 last occurrences in a long stream of them, but seriously, how can the guy win?
I'm not saying Vince is blameless, but it is very 2-sided, and compared to other behavioral problems around the NFL, Vince's is far from major. He is a great teammate and leader, but had a problem with an overrated, egotistical coach who was trying to get rid of him behind his back.
Passing ability/accuracy/QB intelligence: At the beginning, this was a fair criticism. However, anyone who still uses this against Vince clearly has not watched him play in the last two years. Vince has made huge strides in the last few years as a passer. This is very evident by watching his games, but if that's not enough, just look at the stats: 2 years ago his QB rating was in the 80s (ok, only solid, but that was while taking an 0-6 team and going 8-2 the rest of the year). One highlight was his 99-yd 2 minute drill to beat AZN. Last year, before being injured, he had a top 5 QB rating of 98, and the Titans were the highest scoring team in the league--during this time, CJ was nowhere near his level of the year before, and as any Titan fan will tell you, VY looked great and the offense moved far more efficiently through the air than the ground.
Keep in mind that throughout all of his years in TN, he has only had CJ for these last 2, and his WRs have been terrible (best one has been Britt last year, in his second year as a pro..but still no Brandon Marshall)
I think Intelligence is hard to prove without being in the huddle, but I would not just take ESPNs word on rumors like that..VY may not be a genius, but again, he showed huge improvement in the passing game--both in accuracy and making the proper reads, checkdowns, etc.
Work ethic: Again, this could be an ESPN gossip thing, but even if somewhat true: He is playing for a coach and fanbase that he hates and hates him. That will definitely suck some motivation out of you. Also, work ethic is something that can be changed quite easily, as has happened for numerous athletes in the history of sports. Get Vince in a good situation and this probably isn't a problem.
Miami: To touch on the "good situation" thing, Vince apparently loves the city of Miami,
Wins: In the end, what matters more than this? 30-17, among the best in the NFL. He has proven to have that "X-factor" or clutchness as shown in college and in numerous NFL comebacks (ex: AZN above). I know this is a used-up argument for VY, but it's worth noting how many times he has turned TN around from terrible starts to great finishes and vice-versa. People like to "debunk" this by showing his record vs. .500+ teams, which is around .500--BUT, if you compare this to all of the QBs in the league, Vince's record is again among the best of the best, behind only a few like Brady, Brees, Manning, etc.
Mobility: Skills go without saying, but he has actually run a lot less in the last few years. In fact, many TN fans probably think he should have run more at times in the last year or two.
Value vs. other FA QBs:
Here's how I look at it:
1. Don't have to trade away a pick or anything.
2. Salary will likely be lower than Palmer, Kolb, and others.
3. Maximum upside--talent has never been a question. If he's happy and working hard, he could be a great one. Plus, he should be hungry.
4. Younger (no pun intended) than most of others. Palmer, Hasselback, Bulger etc are all getting up there, on the downswing, and are not long-term options. Vince could up being a long-term guy if he works out. (I mean seriously, people would rather sign Hasselback???? That guy is sooo washed up)
5. More proven and ready to play than Kolb (I still don't understand the hype on this guy), or a future draft QB--He's won games and played well, just needs a better situation and coach.
All this said, I don't know why we wouldn't bring Vince in on a 2-3 yr contract, give him a shot and see what happens. By the time other guys develop, all our other weapons could be gone. Worst case--You lose a relatively small amount of money on a failed signing, and then draft another one with a likely high pick. Best case--You just got a dynamic franchise QB that will win games and be a deadly/unique/exciting weapon in the backfield, ultra-cheap and ready to play from day 1.
Given everything else, Palmer is the only other guy I'd consider (depending on the price-both salary and trade), but none of the others seem like good options to me.
