The Miami Dolphins as of the moment have 4 quarterbacks on their roster.
Chad Henne: The quarterback that filled in for Pennington last year when he went down to injury. Chad showed some great strengths, mentally and physically. He showed leadership, nerves in pressure situations, arm strength, etc. But he also showed weakness in his accuracy. He overthrew some balls, giving interceptions, ultimately giving away games. Most are to believe he will work hard and have a progressive off season. This year will decide if he is the real deal or just getting the fans excited for nothing.
Chad Pennington: It's hard to imagine that this guys is 3rd on the roster spot, but don't forget he is still an amazing quarterback. He is 3rd on the roster because he will be mainly mentoring the young quarterbacks as well as prove he is ok after his 3rd surgery on his shoulder. Chad is an extremely smart quarterback, and will come with great leadership on and off the field. He was a great sign for 1 more year.
Pat White: The 2nd round pick out of West Virginia University, in some peoples minds would be a complete bust. Well, I HIGHLY disagree with you. Pat White had the hardest job on the team this past year. He would sit cold on the bench for a whole game and then be asked to come in for a couple plays. This shows that the Miami Organization has a lot of confidence in the kid, but it is hard to get into a rhythm with having only 2 snaps in a row. Some people would argue he never completed a pass his first year. This is true, but he had only 5 attempts! He was also a rookie and not every rookie goes to an AFC championship game like Mark Sanchez. I think the Dolphins didn't take full advantage of this valuable player they picked in last years draft. Put him in for 1 quarter of a game and see how he does. Being mentored by Chad Pennington he can only get better. This guy is an incredible athlete. Don't look down on him yet.
Tyler Thigpen: I don't know what to say about Tyler. I think out of the 4 he has the least amount of chance of getting on the roster come August. He showed some good skills when he came in the last game of the year, he also has proven more than Pat White. The reason he will most likely be the one to go is because the Dolphins could get something for him, rather than Pat White. Pat White I fell they are still finding out his capabilities. Tyler helped, but he is of no need now. Maybe the Bills will be interested?
So the question is who backs up Chad Henne? Tyler of Pat?
