This report from Yahoo Sports suggests that Boston Celtics assistants Tom Thibodeau, Armond Hill, and Kevin Eastman are supposedly being considered for the coaching job.
Thibodeau is a New England native and graduate of Salem State. He has spent time as an assistant at Harvard before joining the Celtics. Armond Hill is my personal favorite, but probably the least likely to take the job. I actually met him at a BC basketball game this season. Eastman has extensive college coaching experience on his resume.
