You can't blame Osweiler for taking the money. Elway screwed things up with Elvis Dumervil years ago, & now he's paying for this too. My left field prediction for the Broncos is, forget RGIII or Colin Kaepernick, the Broncos will go after Johnny Manziel(Von Miller has been his biggest advocate for getting a second chance), at least for a training camp contract, once his legal troubles dies down. Why would they do such a crazy thing? Their current QB on the roster is Trevor Siemian & the only other option for QB in the free agent market is Ryan Fitzpatrick.
Edit: Upon further review, the Broncos have had a long history throughout their entire existence of going with QB's in their mid to late 30's(Charley Johnson, Craig Morton, John Elway when he finally won his 2 Super Bowls, & Peyton Manning. To clarify, they've used QB's in their mid to late 30's during their greatest successes on the field. So I can see them signing Ryan Fitzpatrick, because he fits the mold of that "seasoned veteran" that the Broncos like.
If the Broncos can be patient & wait a year, Carson Wentz will be the next ex-Cleveland Browns QB, but seriously, I see the NY Giants having a fire sale after this upcoming season & wanting to unload Eli Manning.
