When Hewitt first came to Mason I think it was pretty obvious what his intentions were. In his first season Hewitt inherited a winning team built by Larranaga. He was probably hoping he could win lots of games under Mason, get attention from an ACC school and leave to become a big conference coach again.
Obviously that didn't happen. Dissapointing season records and no NCAA/NIT is the reason why Hewitt is not able to find himself a life boat (offers from other schools). If he did get an offer from another school without a doubt he would leave ASAP and get away from the George Mason life boat that he is responsible for sinking.
2014-2015 season will be the last season for Hewitt, keeping him until 2015-2016 would just produce the same results
. Even if we have a winning record in 2014-2015, I would still want the new AD to replace Hewitt. Maybe we can grab Brad Stevens when he gets fired from the Celtics.
