Although it still may be too early (it is) to tell if Jae Crowder will be an effective NBA player, everything about him points to him being a potential steal for the Mavs in the second round of this year's draft.
Crowder has been great for Dallas in the preseason so far, even starting two games. Crowder, in only 18 minutes a game is scoring at nearly 10 PPG, while securing nearly four rebounds and most impressively grabbing 2.17 steals per game.
2.17 steals in 18 minutes is a pretty astounding number in and of itself, but it just exemplifies what kind of player Crowder is. Although he won't ever set any scoring records, Crowder won't be outworked by anyone on the court, and that mentality should allow him to be a huge success in Dallas.
If Crowder can repeat what he has done in the preseason (and there is no reason why he shouldn't), not only will he be in the rotation, but he will be a huge contributor to the Mavs in his rookie season.
