the old rule was if the player just made the pro-bowl youd be doing that pro-bowl multiplier instead of the position multiplier, new rule is you do the pro-bowl multiplier with the position multiplier.
So before
a 90 QB 29 years old signed for 1 year would cost (if he made the probowl)
6.5 x 1.2 x 1 x 1 = 7.8 ovr x probowl x age x contract
now its (using the same example) 6.5 x 1.1 x 1.2 x 1 x 1 = 8.58 ovr x position x probowl x age x contract
