How the Coaches Judge Defensive Players

From Scott Wolf's blog:

Tackle 2 points
Tackle for loss 3 points
Sack 4 points
Interception 4 points
Sack causing fumble 6 points
Forced fumble 4 points
Fumble recovery 4 points
Block 4 points

Missed tackle -1
Missed assignment -1
Critical error -4
Penalty -2
Loaf -2

Interesting way of looking at it.  The only thing that struck me as odd is the equal amount of points given for forcing a fumble and recovering one.
