ImO, signing a retread QB isn't the answer. Lets start by evaluating the three guys we have. If Tebow is never going to get a shot at QB, the release him and admit the team didnt think the acquisition through and then mishandled him tremendously.
Next, have Sanchez battle McElroy with BOTH QBs getting an equal opportu ity to win the job.
Then I draft Manuel in the second AND Renfree in the 7th. So we end up putting Renfree on IR during the last week of preseason and go into the season with McElroy, Sanchez, and Manuel for 2013.
Then McElroy, Manuel, and Renfree in 2014.
