Has nothing to do with what the Dolphins did. It is common sense and HISTORY that proves taking a quarterback in the first round in back to back years never really happens. Like I said it happened once in the 80s(because the first QB was suspended for his second season) and then the next case was in the early 60s. A catasrophic injury, something like a career ending injury, sure there is the exception for taking another QB in the first round. Since that probably won't happen, I don't think there is any justifying taking another 1st round quarterback. I am sure there are some talent evaluators who would rank Tannehill ahead of him, just like there were some that ranked Tannehill ahead of RGIII. Not saying that the majority did, but some did. If you take another first round quarterback, it isn't creating competition at the position, you are basically kicking Tannehill out the door, therefore have WASTED a first round pick. Do you kick Barkley out the door in 2014 if there is a better QB on the board in the following draft? Then kick that guy out in 2015, and so on?
Good for him that he might win the Heisman Trophy. Tim Tebow won the Heisman also.
So what if he struggles in a short window this season? Matthew Stafford sucked his first season, didn't do anything of note in his second season but became a stud in year three. They drafted Tannehill based on potential and his tools and project him as a starting QB in the NFL. He is probably the most raw QB that was taken in the first round and needs time to develop. A couple of games in his rookie season is not enough to make a final determination on him.
What if Tannehill becomes a star and Barkley is a bust? How do you justify taking a second first round QB who was a bust and not using that pick on a weapon for Tannehill? We don't know how either will turn out in the pros but you can't waste a pick so soon because you are afraid. They made a commitment to Tannehill, and it is their responsibility to make sure he is put in a position and given the proper weapons to make sure he succeeds.
You can't even compare the Brees and Rivers situation to this. Brees(a second round pick) was already with the Chargers for three seasons and had career stats of 29 touchdowns and 31 interceptions. So yeah, after three years of mediocre play it is justified to start looking at other options. You are talking about adding Barkley before Tannehill even enters his first training camp.
