Thanks for the responses, folks. It was a really hard decision, but I ended up going with player 2, partly because he was cheaper to recruit, but mostly because of his potential for positional flexibility. With his BH / PAS combo, if his SPD is high-high, he's going to be workable at either guard spot. And if his REB and PER are high-high, he's easily playable at the 3. For player 1, the defensive potential is huge, but I worried about the SPD and PAS.
As tianyi and others mentioned, this is really going to come down to how high Player 2's high's become, esp in DEF and PER.
