I personally would like to have blount more even if hes out till week 9. you have enough rbs to hold onto blount. can't really go wrong though.
Here are the playoff matchups (wks 14, 15, 16)
Tolbert: buf, balt, @det
Blount: @jax, dallas, @carolina
Tolbert has the better matchup in wk 14, but not a good one in 15.
