Hello, been checking out this thread, and thought it might help to give things from a 49er perspective. It is to the 49ers advantage to keep JG this year and play him. 49ers want to contend for a Super Bowl, which is hard to do with a rookie. The 49ers are also investing a lot of draft capital into a single player, they can't afford for it to fail. The best thing for a rookie QB is to sit a year and learn behind a vet (and Kyle's offense is more complicated than most).
I even started a
poll on a 49er forum. 50% wouldn't trade him for any price, 20% would trade him for a first, and another 30% would trade him for a second or better. Of course, fans aren't management. I suspect that 49er brass would trade him for a first despite the advantages of keeping him based on them saying a trade was possible.
Biggest issue for trading JG (other than his no trade clause) is his salary. He is being paid like he is one of the best QB in the league, but his play/health history doesn't match up to it. If he is cut, no one will pay him 25 million a year. I expect JG will play for the 49ers for a year, and either prove he is worth his salary and be traded, or fail and get cut. So if you can wait a year, you might get him for free.
