The point about Magic is that he gives you a lot of boards from the PG spot. Putting him at SF would defeat the primary purpose of what makes him worth a damn in this sim. Scott doesn't shoot enough 3s, especially when you're limited in your player pool and the one position you can get a ton of 3s out of in the Gym Rat (lakers) is SG.
$47M cap, eh? That makes defense slightly more important, but nowhere near as much so as in a $52M cap. I'm pretty sure I do a bomber platoon at the 2, 89-90 Magic starting at point, Shaq at C, 68-69 Wilt at PF (or vice versa) and then think long and hard about who I'm putting at the 3.
In the current scenario, I might try Landsberger + Rodman at PF... that gives you 30 minutes a game at high reb%... not sure what after that, but this is all off the top of my head anyway.
