I think this team realized a while ago that "you move the ball or you die", and last year playoffs' drove the point home. When this team is engaged and moving the ball side to side, they're really good. I think Tim realized a long time ago his post game is not as effective as it used to be. He naturally moved to the jumper a couple seasons ago, and now he's just a part of the passing game.
The two guys that get to the rack consistently for this team always have been Tony and Manu. Tony was hobbled until about two weeks ago, but he seems to have regained his speed, so I expect him to attack the basket more going forward. Manu, more or less always drives, with mixed results. He's obviously past his athletic prime, so you won't see big finishes at the rim, but he can get there. Cojo and Kawhi are more of a mixed bag. Cojo hasn't played much anymore, and Kawhi it's hit or miss, something he settles and sometimes he drives. His footwork is still awkward, but his jumper has improved.
The real question, IMO, is how much of this is 'holding back' and how much is real decline. Driving, creating contact, etc is all wear and tear, so it makes sense they would scale rit back a bit. But we'll find out in just a few weeks.
