Through 10 games, BC has only returned 10 punts. That is the lowest in the ACC. The only other BCS team that has only returned 10 punts is Syracuse and the Orange's D is so bad they have barely been punted to.
Not only did Tribble fail to attempt many returns, the returns he made have generated very little yardage. His 10 returns have gone for just 47 yards for a 4.7 yard average. The only BCS teams with worse average returns are Iowa State and the beleaguered Syracuse.
I hope Tribble comes back strong in the bowl game but I think Silva, Challenger or Mulrooney (the likely candidates to return punts) will be an improvement.
