there was a reason for keeping the MLE, and that is to use it! if the pacers are lookiong for a center that will sign for MLE or less and still be starter quality then my advice is to look at greg ostertag.
check his stats before telling me he is too doofy, or a slug. the fact is he produces and he has a high EFF rating. he is a good rebounder, shotblocker, and post defender. IMO would be a very nice pick up.
