I wouldn't say Manu is past his prime, yes he is more prone to injury and yes he will only be in his prime for the next 2 years at the most. But if last years end run to the playoffs and playoffs was any indication, where he practically carried the team. you have to project : Manu in the playoff stretch will be as good as ever. He won't be playing at the level for the whole season. but does that matter ? Don't worry you can count he will be at his best when it counts.
Tim I agree will not be the same dominant force he was even if limited to the playoffs. ( that's the biggest drop off)
Tony should be as good as 07. I see Dice doing a horry ( resting until in matters :playoffs) . RJ although a year older should be a lot better , with a year to learn the system. same goes with HIll and Blair.
So it comes down to this: Hope Timmy does not have a significant drop off in the playoffs too big for new guy Tiago to make up for.
