Also, Wallace will be an UFA this off-season with no draft pick compensation if he signs elsewhere.
And there is no such thing as an "extra pick" anyway. You have the picks you have. A second third round pick comes with the same opportunity cost as the original, as you are forgoing the next possible starting linebacker, safety, running back, etc. for a man that will hold a clipboard for 4 years before leaving to another team.
Finally, let's say you are correct and the Steelers backup will get a game or two a year. You are talking about a kid who only sees snaps in LaTrobe coming in and bailing out the team in weeks 11 and 12? LOL
Flynn was a 7th rounder, not a third or fourth as you would have us use. I would also point out that he beat out Brian Brohm for the Packers backup QB spot, a SECOND rounder. In other words, even using a pick that high can result in getting crap.
Flynn left as a free agent (no treasure trove of compensation for the Packers) and cannot even start for the Seahawks.
Now, let's play hypothetical.
Is there anyway you see a rookie backup QB winning a game where his team fumbled five times (not to mention all the holding penalties)? No way.
Batch did not do anything exemplary to win the game but he is not the reason we lost. The entire OFFENSE sucked and he is just a scapegoat.
