1) what do they plan to do with tebow? do they actually plan to let him go? I'm not so sure right now. Marty's interview speaking to low completion percentage was perceived as about Sanchez. But he also spoke to building around your players strengths. Was he actually referring to Tebow? All things considered I'm somehow not totally opposed to giving him the job so long as it's not a "specialty package" deal and he is just given the job outright. You either go all in with Tim or or don't go with him at all. If him starting is not an option they need to get rid of him.
2) do they plan to draft a QB? if so thats Sanchez, Tebow and drafted QB. We could of course bring in a 4th for competition purposes, but I think assuming 1 and 2 happen it would be between these 3 guys.
I'm not sure the Jets are going to sign a QB in FA...It really depends on what they plan to do in the above IMO.
If they do they want to go with a FA, and Orton becomes available I agree that he would be the best option.
