That can't be true I've read here multiple times that Scott Pollard provided more to last years team than POB has to this years team. Of course I remember him being hurt the whole year as well.
While he was injured for much of last year, he still played in 22 games, and was part of the rotation for a good number of those. POB has done nothing like that.
When healthy, Pollard is a decent backup center in this league. Unfortunately, he hasn't been able to stay healthy for a while.
