ESPN has made some changes to their formula for total QBR, which has become a widely used metric to evaluate quarterbacks.

How interception returns, pressure and credit for yards after the catch are factored were changed.

Russell Wilson's QBR increased by 8.2 points, moving him from 12th to eighth in the rankings. Wilson was one of the top players in the NFL when under pressure.

Aaron Rodgers' QBR decreased by 5.2 points, but he remained ranked second. Rodgers' QBR decreased due to how the new formula handles yards after the catch.

J.J. Watt is the only player to record 40 or more quarterback hits in a season since 2000 and he's done it in three straight seasons.

Watt had 50 quarterback hits in 2014, which was first in the NFL well ahead of Carlos Dunlap's 28 and Von Miller's 27.

Watt had 46 quarterback hits in 2013 and 43 in 2012.

The next highest total of quarterback hits in the NFL since 2000 came in 2013 by Robert Quinn and in 2012 by Cameron Wake with 33 apiece.
