Rather than just looking at last night, let's look at the team as a whole with 2 games under our belt. I will cut a little slack for triple option.

D-line - B
LB - C-. Another year of poor help on pass defense.
CB - C. Not enough data yet.
S - B. Tackling is suspect, but Vonn Bell bump.

QB - C
RB - C
WR - D
H back - C
O Line - below F. obviously affecting QB, RB, etc.

Kicker - C
Punter - B
Coverage - C+
Return - C-

Playcalling - D
