The 25 Best Seasons by a Quarterback (using current QB Formula)

Here are the 25 best seasons that a quarterback has had in the NFL (since 1940) using the current QB Rating system.  I have previously mentioned my dislike for the system.  However, for now, this is the list.

Note:  This list is slightly different than that shown at The Pro Football Hall of Fame.  The HOF has Bart Starr's 1968 season at #19 with a Rating of 104.3.  I did not include him here as he didn't "qualify", having only attempted 171 passes.  For 1968, I used 14 attempts per game (or, 196 for the season) as the qualifier.
