Barkley isn't even in the conversation for the Dolphins after the they took Tannehill. The object going forward and in next year's draft is to give Tannehill a better supporting cast to make sure he is successful when he does eventually become the starter. They are not going to replace him after one year or bring in a 1st round QB in 2013 to compete with him. They will probably draft a QB in 2013, but as a mid-late round prospect to be Tannehill's backup.
The Rams had a shot at RGIII this draft, but continued to build the team around Bradford. The Jaguars could have taken Tannehill, but decided to give Gabbert a weapon to help him continue to grow.
You can like Barkley better, that is not what really is the topic though. The Dolphins committed to Tannehill as the guy they see as the franchise quarterback of the future. If Andrew Luck struggles(as expected) this season and Barkley is on the board when they pick next April, should they take him? Or do you get Luck a big time WR, or a running back, or maybe some offensive line help? Or maybe do what the Rams did and trade the pick for multiple 1st round picks?
Look, I understand the Tannehill is raw, has some questions that need to be answered and in the end might not turn out to be the franchise quarterback the team thinks he is. Really any of the four first round quarterbacks might end up being duds, but after you commit to them your job becomes making sure you do everything possible to have them succeed. It isn't about replacing them just one year later. Tannehill had limited tape for teams to evaluate him, but Miami had the (unfair?) advantage of having his college head coach as the offensive coordinator. You have Ireland who had been scouting Tannehill extremely close the past couple of years, have Sherman's first hand evaluation and have a head coach in Philbin who has a track record of developing quarterbacks in the NFL. Maybe they all turn out to be wrong and those without all the inside knowledge on a message board(us) turn out to be right. We will just have to wait and see. What we do know is that Tannehill is extremely smart, very athletic, strong arm but ultimately raw because of limited starts in college. There are a lot of unknowns because he wasn't a two, three or four year college starter, but he does have the tools to become a big time quarterback?
