I'm sure in the contract negotiations the Cowboys brought up his fumbles and his injury history. I think Murray though would at least want an incentive laden contract similar to Sean Lee's.
And I'm guessing that will be the middle ground here.
Murray will want the capacity to earn top money, while the Cowboys will want in out if things do not work out.
They've been pretty creative with contracts lately, if you look at Sean Lee and Henry Melton. That being said, this could go down to the franchise tag, maybe even two years in a row.
There are a couple factors at play.
#1 Adrian Peterson
#2 Dez Bryant
If Peterson is available, the Cowboys might make a move to get him behind this line for a couple years. If Dez Bryant can't be resigned this year, he might command the franchise tag.
