All signs are pointing to Phil Bennett taking the Texas Tech DC job. There hasn't been much activity from Texas Tech's side in filling the vacancy which indicates that it is Bennett's job to lose.
With the departure of Bennett to his alma mater, this opens the door for Greg Gattuso to take over as DC at Pitt. I would like for Pitt to search outside of the program for some potential candidates instead of just handing it to Gattuso, but that might not happen.
There are internet message board rumblings about Sal Sunseri possibly joining, but that is a pipe dream at best. Sal Sunseri's salary at Alabama (base + bonus) are much higher than what Pitt would pay. Also, I believe that due to Tino being a sophomore, Sal would not want to join the staff due to any type of pressure or resentment that might develop with him on staff. Lastly, he is coaching on a team playing in the national championship. While we all love Pitt, we're not at that level yet and it just makes more sense for Sunseri to not leave Alabama for Pitt.
There hasn't been any word on Bossard or Tumpkin yet. Some players feel that Bossard will be back despite persistant in-season rumors that he would be relieved of his duties at the end of the season.
