I've read some stuff on Wall but given what I saw from Rose as a rookie in the playoffs, I'm going with Rose until I see Wall play a college game.
Also, apparently the kid has already had a run in with the law on a breaking and entering charge. Could be a clue that his head isn't where it should be and might never be. On the other hand, John Calipari will be coaching him and Calipari coached Rose, so after a while we should be hearing all the comparisons with Coach Calipari having to answer the "who's better" question about a million times over the next year or so.
