I believe it is not fair to judge Streveler right now, the guy had MAJOR knee surgery...he can't be 100% wears a huge brace, this affects, mental and physical aspects. Will he ever become a great starter, possibly not but please remember the severity of the knee injury he recently suffered...
I have been recently hard on Hogan, and I don't have much faith he is "helping" Streveler at all.
Finally, as has been pointed out look at the o-line, how many hits has Zach taken this year compared to his years past in the Peg......look at Brady, Logan, Demski, Strev. when the do run rarely do the get holes, the only time it seems they have a good run is when they do it themselves and break tackles, or "juke" a defender or three.......is it all the players, I am sure a portion is, but again I question how much is also on the OC.
In short, I don't care if is Zach, Wilson, Streveler, Elegsmaera, I don't think any of them have a great chance with the talent and schemes they have to work with.........sorry but those crying for a new QB, even if you get your wish, it won't solve the offence.......
