The obvious is that football is still won in the trenches, esp. with a young QB under center.

Having your young QB throw 40+ (much less 50 times a game) is usually not a recipe for success.

Guess neither Mariota or Winston are the long term answer at QB for their respective franchises.

Mariota is 0-4 when he has had to throw 40+ times in a game, one being this season (thus far).

Winston is 0-7 when has he has had to throw 40+ times in a game, 2 of them coming this season.

And both Mariota and Winston have more experience than Siemian.

There are going to be "growing pains" with a young QB, esp. if one asks the young QB to "wing it" and there are issues at the O-line and/or the lack of a 3rd (much less 4th) pass-catching play-maker (at the TE or slot positions).

Is Derek Carr the "long-term answer" for the Raiders?

Carr hasn't exactly been lighting it up this season and is 3-11 in games where he has had 40+ pass attempts.
