It would seem for now there are two obvious directions that Chip Kelly may be developing with the decision to resign Vick to a one year deal..
Option 1: The Alex Smith Approach - Basically Vick has been resigned because Kelly believes that he can get a talented QB in the 2013 draft, but not one that will be immediately pro-ready. If this is the plan I think it suggests three potential candidates: Ryan Nassib, Tyler Wilson or EJ Manuel. None of the three looks to be a can't miss contender but I think you could make a case for anyone of the three having a chance to grow into Kelly's new offense. Vick would start the season and the rookie would either win the job during the season or be ready to start in 2014..
Option 2: The 2014 Solution - As things stand the crop of QBs for 2014 looks stronger than this year. Again there seems to be three leading candidates: Teddy Bridgewater, Logan Thomas and Tajh Boyd. If Vick is gone you'd have to presume that if the plan is to get someone next year then they will need to be pro-ready (although it's way too early to judge I don't see Thomas projecting as a Day 1 starter in September 2014)..
Having thought about it I suspect the current thought process is around option 1, otherwise you are gambling on either having a poor season or being able to pick up a athletic quarterback who can start on day 1 in the middle to late first round (anyone think that’s possible?) or being able to trade up into the top 4 or 5 picks. With all that in mind, and despite Chip’s statement that the quarterback landscape isn’t great I think the chances of the Eagles selecting Ryan Nassib with the 4th pick in the 2nd round is looking increasingly possible.
