Yeah, it happens some of the time, but most of the teams that "tank" stink anyway. It's not like there's a huge wave of potential play-off teams that are packing it in too early in hopes of getting a shot at drafting the next superstar. The bad teams are consistently bad all season. If they bench their "best" players the last eighth of the season it hopes of improving their draft position doesn't change the fact that they also sucked legitimately for the other 7/8s. Most of these solutions are killing ants with elephant guns.
