Because I think he's the better player. And i don't think there's any hype for Giddens, just a couple of people that like him, hardly hype.
Good defender, good passer, strong finisher, high energy, long arms, blocks shots, unselfish, highly athletic, great rebounder, can post up. Even so, needs to work on his jumpshot, freethrows, and a bit on his defensive footwork and probably his rotations, and ballhandling (which he shouldn't be doing much of anyways).
