Time on the Dukies side...shocker

Was watching the Dukies try to give Clemson the game last night and watched that clock fiasco live. It seemed to me like the refs added too much time but since nobody seemed to bitch, neither the annoucers nor Purnell, figured I was wrong. The today, eeeeeeeverybody is yelling about it and now the ACC admits their mistake

Seriously, how many times can the refs, whether intentionally or not, hook a team up???
