I had a similar thought, as well. But then I realized that Lewis is 6-10 with a good vertical leap and a rebounding front line of Lewis, Amare, and Marion sounds just as effective as one that includes Diaw, Amare and Marion. The combinations are endless and the scoring he could provide from the 3 or 4 spot is incredible.
My point is - like Simmons's - that the Suns would be the most well-rested team in the world because no one would have to play much more than 30 minutes per night. All someone has to do is motivate Rashard to rebound in Marion's likeness (i.e. timing and hustle - to the tune of 7 or so boards per game) and they're golden.
I also think, and Bob Lanier disagrees with me, that it is quicker and easier to motivate a player and teach him to scramble after rebounds (especially with a coach like Ivaroni) than it is to teach that player how to shoot. I'd still love to have David Lee more than anything in the world, but I fear that's a big pipe dream because I don't know how they could pull it off (even with Isiah on the other end). I also think that Rashard Lewis could provide so much more offensively than Lee and maybe add that extra element in a half-court game (and I don't think Lee could hit that 15-ft jumper like Kurt Thomas could).
I just don't know if Lee's hustle and rebounding will be that beneficial in the long haul of a whole series with the Suns' style of play. However, I'm in no way trying to discredit his value or his game, because I love the guy's old-school nature. It's just I'd never really thought of Rashard Lewis until Simmons brought it up, and I started looking at stats. Then, I realized that with the proper direction, he could probably turn into a really good player. Then again, so could Lee, but I think Lewis would provide the most immediate help for 2007. Still, I don't want to part with Kurt Thomas because I still feel he is valuable to the Suns in more ways than stats can show.
