He very easily could have severely injured Barea. It wasn't even a tough foul at a critical part of the game, which you can somewhat understand. He should be sent a huge message, double digit suspension.
During the 09-10 season, 5 games separated 2nd and 8th place in the West. My guess is that with the shortened season, 5 games could be a big difference.
And Bynum should have been suspended longer for his punk move, especially given that he did a similar thing to Beasley.
