What do you do after you score 20 points and 8 rebounds in a breakout performance, then get asked by an NBA GM to stick around  for a few days to continue playing?

That’s an easy one to answer: You hop on the next flight to Vegas.

Even though Danny Ainge’s offer to have Janning stay and keep playing for the Celtics summer league team was mighty enticing, Janning’s agent ensured him he couldn’t renege on his commitment to the Phoenix Suns. Janning had already been schedule to play with the Suns in the Las Vegas summer league.

The C’s looked into keeping Janning around a bit longer, but his agent, Frank Catapano, said he couldn’t go back on the commitment to the Suns.

“It’s tough, because obviously you’re looking forward to getting out there and playing a few minutes and seeing everybody else,” Janning said. “But after a day like today, you kind of want to stay and enjoy this trip a little bit.”

I don’t know if Janning will ever make the NBA, but he impressed the hell out of me yesterday.
