ESPN’s John Hollinger has your answer to the Game 5 question:
The problem is any hit to the shoulder presents a risk, and that’s a double problem because of how Portland wants to use him. Ideally, the Blazers would like to put Batum on Steve Nash, but the Suns run pick-and-roll on nearly every play – which means they’re putting Batum’s shoulder at risk of smashing into a screener on nearly every trip.
That’s what happened to Batum in Game 5, causing a setback that sent him to the sideline icing his shoulder, which is why he only played 20 minutes. It’s also why we didn’t see Batum on Nash in Game 5, and why we probably won’t see it before the fourth quarter tomorrow.
Of all the rotation issues in that game, this was the most befuddling, so it’s nice to have an answer, even if it means more problems for Batum. If only we could discover why Webster hardly played until the second half, and why Rudy is getting more of a cup-of-coffee chance anymore.
