I can't see Kaep starting for any NFL team, as his decision making and accuracy are both poor. Perhaps he could convert to WR, like Terrell Pryor? As to teams not wanting him because he's a distraction, I don't buy that for the same reasons Michael Sam wasn't a distraction to the team. The teams know who he is coming in. You can control that, prepare for it. This isn't the same as a Johnny Manziel distraction either, where you don't know what can happen on any given day. Kaep definitely won't go to Buffalo though. Not just because it's an industrial, working class city, but because they have Cardale Jones they want to develop.
As to Rivers, he's aging, but has been durable much of his career. Would Elway sign him at $15m or so per year, and let Lynch sit for two years? That seems unlikely, but you never know.
The 49ers are a mess, so whomever takes that job better get along with the incoming GM, and demand patience from the Yorks, as the team is at rock bottom, with no QB, and no big QB in the draft right now to draft. Not much of a roster elsewhere either. Maybe they'll get the first pick in the 2018 draft as well and find a QB there?
Gabbert is the QB that seems in no mans land, but he, more than Kaep, looks like a solid backup in this league.
Chip has said several times he doesn't want to go back to college, but I agree he should. His schemes are simply much better suited for the college game, and he'd forever have a HC job, most likely with a high profile school.
Jordy Nelson participated in light practice for the Packers. Even if he suits up and plays, how effective will he be on Sunday? Can anyone picture him running a crossing pattern into traffic with broken ribs?
