By the way, if you get great DEF ratings across the board and put in 20+ practice mins on M2M right from the start, you don't necessarily HAVE to recruit great REB. If you have awesome perimeter defense, you can often play "-" defenses to pack it in inside and boost your reb stats. My Wisc-Superior just finished a season with 6 freshman plus a walk-on, and allowed 29% 3PT the whole season - even though I played -2 and -3 in most of my games. The key was having 3 guards / SF's with defense ratings of 63, 79 and 87, respectively.
Don't get me wrong - REB is still a great-to-have, esp for your big men. My point is just that you can build a really good M2M defense in D3 from the inside-out or outside-in.
