I love Ray, if he were 100% healthy right now, I might consider starting him against Wade.
This being said, when Ray was healthy last year, Wade destroyed him. It's not Ray's fault. He's a 37 year old off guard trying to guard one of the sneakiest, most herky Jerky, younger offensive off guards in the league.
The main reason I'd give the nod to Pavs is because Bradley's youthful energy is what gave our starting unit such a boost over the last half of the season.
With Rondo, Bass and Pavs and odd as it may sound, a very fast and athletic 36 year old KG "at the center" position, where he seems faster than any center he goes against, we have some juice in that starting lineup. Pierce tags along at a respectable level at the three as well.
You put a banged up Pietrus or Ray in there and we're going to get bogged down. Lean on the young legs as much as you can.
