Downshifting bad?

The other day I came running up to the skeet range at a decent pace and when I started to slow down, I dropped from 5th to 4th with a little throttle bump to ease the shift before I slowed to turn into my parking spot. The range manager is a good friend of mine, and he commented that downshifting a turbo diesel is really hard on the engine bearings and especially hard on the turbo bearings. He's fairly knowledgeable when it comes to heavy diesel equipment, and had a military license to drive just about everything the Air Force used to inventory, so I'm sure he believes what he's saying, but I'm trying to see how it could be a problem. Should I not try to match engine speed to tranny speed during downshifts? Should I just not downshift while slowing down at all? Or am I even hurting anything?

Thanks all,
-Adam
