I like all three changes, last season OD got tired and we could all tell, so giving him a game off here and there should keep him fresh. And Carolina doesn't really have a heavyweight iirc so no need for rat boy.
Ok, slightly off topic here but I want to know how many of you guys that keep saying that OD was tired last year or that he needs rest are even OD's age? Take it from a pretty well conditioned 46 yr old man, there isn't a whole lot of difference as far as conditioning or performance from 20 something to 30 something like so many of you guys seem to think. There is some dropoff once you've reached 40s and yes, I needed more rest than a 20 yr old but during 30s and even in my early 40s, my friends and I were kicking the **** out of you youngsters in 2 man beach volleyball.
Don't buy into the media bias. Watch the game with an impartial eye.
