why would TT or peppers redo his contract after just the first year of a 3 year deal?

peppers signed the deal with a very cap friendly first year, and took a big paycut to do it, knowing if he played well, he would make his normal wages in 2015 and 2016

he pocketed 8.5 million for last season, he can make 9.5 million next season, and 8 million in 2016

looks to me like a deal set up to play out until he runs out of gas and we cut him
