The RT contract decision does not have to come until after next year. With the cap projected future increases, the money is not going to be a problem. His being worth paying is the question, and I believe that decision will be made after this year. IF he does not progress, I could see QB as a high draft pick next year, possibly #1. We will not find an option in FA.
I just do not see many QB's that are better ability-wise that could be available.
