4th quarter passer rating in my opinion is a huge determinant to indicate which quarterback has the best potential to win games when "the game is on the line" or in reverse to prove that pressure of performing in the 4th quarter "is not too big for that quarterback."

With that in mind any quarterback passer rating under 75 is below average, 75-90 average, 90-100 good and over 100 excellent. With that in mind here are the rankings of the 2011 starting quarterbacks as of week 12:

EXCELLENT:

E. MANNING------------------123.7

RODGERS--------------------113.0

BRADY-------------------------108.4

TEBOW------------------------107.8

J CAMPBELL------------------104.1

GOOD:

STAFFORD-------------------98.6

ROMO-------------------------96.9

SANCHEZ--------------------93.8

A SMITH---------------------91.6

BREES----------------------91.2

AVERAGE:

FLACCO-------------------87.3

FITZPATRICK------------86.5

FREEMAN----------------84.3

MCCOY------------------84.0

HASSELBECK---------81.9

RYAN-------------------79.1

T JACKSON----------78.1

NEWTON-------------76.1

BELOW AVERAGE:

RIVERS--------------73.5

ROETHLISBERG---72.4

KOLB----------------72.0

BRADFORD--------71.8

SCHAUB------------69.2

CASSELL-----------65.2

CUTLER------------60.5

MOORE------------60.3

DALTON-----------58.4

PAINTER-----------45.5

C PALMER--------34.8

Bottom line: Tim Tebow is clutch when he needs to be while many quarterbacks need to be ahead going into the 4th quarter for their teams to be assured of winning or at least to have a decent chance of prevailing.
