Mark,
If Blount is an unrestricted free agent, Boston cannot protect him. So that slot could be filled by Atkins. From what I've read, Charlotte is interested in building around young, low priced players so I don't see them selecting LaFrentz if he were left unprotected.
Assuming Blount is unrestricted (I don't know for sure), I'd protect:
Banks Davis Hunter Mihm Perkins Pierce Welsch Atkins
...and speculate that Jumaine Jones gets selected by Charlotte. The
only issue assuming the Celtics are that high on LaFrentz is the
scenario in which the Bobcats take LaFrentz and then trade him to a team
that wants him. For the big money he's making, I'm not sure how
realistic that scenario is however.
