From Ridiculous Upside:
"Ridiculous Upside has confirmed that Marcus Cousin, a 6-foot-11 center, is expected to be signed by the Jazz to a 10-day contract after averaging 14.7 points, 8.6 rebounds and 1.2 blocks in 38 games -- all starts -- for the Austin Toros this season."
As RU noted, he's worked out for the Jazz in the 2009 draft. He wasn't selected but has appeared with the Spurs in 5 pre-season games before he was released.
He's putting up 14.7 & 8.6 with the Toros this season in 30 minutes per game while shooting 53% from the field. He's also an 82% free-throw shooter.
This is an insurance move with all of the injuries the Jazz are going through right now. I'm not sure what his future is with the team beyond a couple of 10-day contracts, but hopefully he can make the most of his minutes and perhaps turn it into a long-term spot, either with the Jazz or someone else.
Cousin has gone from being a decent player at Houston, to a bad player in Turkey, to a good player in the D-League. There was nothing in his professional career prior to this season to suggest he could have achieved what he has done this season, yet playing for the Spurs owned affiliate the Austin Toros, Cousin (Coo-sawn) has averaged 14.6 points and 8.6 rebounds in 29 minutes a game, shooting 54% from the field and 82% from the free throw line. It's not the most fluid or exceptional production, but it's good, and from a hitherto surprising source. Cousin has NBA size as 6'11 and 255lbs, and despite being something of a late bloomer, he's definitely bloomed.
And from Pounding the Rock, (they also have more video highlights),
Cousin went undrafted out of college (any of you sensing a theme here with the Spurs camp invites?), even though he apparently held his own at the Portsmouth Invitational last year - DraftExpress even gave Marcus a spot on their All Second Tourney Team. The Rockets did sign him to their Summer League team, along with PtR favorites Garrett Temple and James White. And this is where the trail peters out. Cousin played in Turkey and Israel last year, but the only stats I've found are these. Not overwhelming numbers by any stretch of the imagination, but at least he spent the year playing basketball.
