It's quite possible, likely, even, that Stidham chose the same basic role and money in Denver as in LV because he didn't want to play for McDaniels.Except for the fact that Stidham signed with the Broncos first for a total of $10 million over two years, 3 weeks before the Raiders signed Hoyer for 2 years, $4.5 million, so it's more like he picked Hoyer over the rest of the flotsam and jetsam instead. And that "injured DE" (that was drafted 7th) has played in all but one game this year and a total of just over 40% of the snaps, which is 2nd most for edge rushers behind Crosby. Has he had a ton of numbers? No, but he's a rookie and there's a steep learning curve at DE.
The bottom line is, one way or another, this is on McDaniels. If he essentially chose Hoyer over Stidham, he was wrong. If he drove Stidham away because of his coaching pedagogics, he was wrong. And if he thought the actual QB in his system doesn't really matter because of him/his system (see the previous quote about a high school QB after jettisoning Cutler), he was wrong.
Again, though, the bigger problem is jettisoning Carr for Jimmy G, which was and is stupid, and not having an offense that can score 20 or more points with all the weapons there.
