For me, Delonte is a combo guard that is competent at running the point as a backup. He can and should excel for this team at either guard spot because he knows Pierce, Rondo, Davis from before. He has also been here the whole season and has had time to get a little familiar with Shaq, KG, Ray, Wafer and JO, even being injured.
I would be much more comfortable with him running our team in the event of injury to Rondo than Nate or Bradley. We saw what that would be like and it was a struggle as Pierce and Ray tried to pick up the slack. Thank god that didnt happen for any great length of time.
