Michael Vick, Keyshaw Johnson, Cris Carter, and Tom Jackson are wrong

about roughing the passer calls and referee bias.  The QB's getting the most calls per 100 passes:

J. Campbell	1.46
J. Cutler	1.28
C. McCoy	1.20
J. Clausen	1.00
S. Bradford	1.00

And the least calls (minimum of one call, i.e. QB's with zero calls not included):

J. Freeman	0.17
E. Manning	0.16
T. Brady	0.16
M. Schaub	0.15
P. Manning	0.15

Michael Vick gets more calls than average, at 0.88.
