Mavs sign free agent center Samuel Dalembert to a two-year, $7.5 million deal. Dalembert has rubbed just about every coach he has played for in the NBA the wrong way, and for yet another season he'll get an opportunity to waltz into a starting job. Whether he'll fail to capitalize once again is anybody's guess, but nevertheless he's well worth watching heading into draft season. Hopefully Rick Carlisle isn't carrying over last year's grumpiness into this campaign.
