Foster is a good back. He's a solid, not spectacular performer, and unfortunately for him his most memorable plays have been against SC in 2005, against PSU last year in the bowl game, against Florida this year, and against SC this year. All fumbles. He needs a couple of signature long and/or tackle breaking, and or game winning runs to swing popular opinion more to the overwhelmingly favorable side of the spectrum.
That being said, he's a good kid who plays hard for Tennessee and I love him for that.
