I think there is a strong possibility he signs another 1 year deal or even a multi year deal with us. He's had so many offensive coordinators and garbage HC's. Now he really likes Harbaugh a lot and respects him. And he's playing better under him. I honestly don't think he would leave to another team for more money. If he can have Harbaugh again he will stay even for a little less money. Rogers and Edwards need to be resigned also.
If Alex wins 9 - 10 games and we win the division and we get to the playoffs for the first time in almost a decade Alex will be back IMO. And he should be. Kaep looks like 3 years away if ever. Do you really want to go through that again? We got a #1 pick finally playing better under Harbaugh. Why not ride with that? It would be absurd not to. And like I said I think Alex will lean toward coming back with Harbaugh if he has success. More money won't mean much to him if it means a new system, new OC, and new HC. He would take a huge risk there based on his history and temperment.
