Naturally, the Grizzlies are looking for more size now that Darrell Arthur (Achilles) is done for the season. Cunningham, who is a restricted free agent, would provide help down low defensively, but isn't much of an offensive threat. Speights, on the other hand, can be a potent offensive threat in the paint, but he's not nearly the defensive presence that Cunningham is. So, here we are, Grizzlies fans. Offense vs. Defense. Who you got?
