There's a difference between not doing well, and not given an opportunity. Rob Ninkovich didn't play well for the Saints. I think John Jenkins was another. Baun didn't really get an opportunity at his most natural, obvious position.
Could it be his "most natural, obvious position" because he's now on a much better team?
People wanted Allen gone (including myself). He's gone. Let him be gone. But this constant rehashing of Baun seemly every week, come on. It's Zack Baun, not LT for crying out loud.
