Stephen A Smith? My guess is this is just an idea that popped into his head while he was on the air, and being Stephen A Smith, he expressed it as fact...loudly.
"NOW LETS TALK ABOUT THE TORONTO RAPTORS. YOU'VE GOT BOSH. YOU'VE GOT O NEAL. YOU'VE GOT CAL-DAY-RONE. NOW JUST WHAT DOES THIS TEAM NEED? THEY NEED A DEFENSIVE STOPPER. AND WHO IS THAT DEFENSIVE STOPPER? LETS TALK ABOUT JAMES POSEY. IVE BEEN TALKING TO SOME PEOPLE (Swag note: not likely) AND THEY THINK THIS COULD BE A DONE DEAL. IT HAS TO BE TRUE BECAUSE I'M YELLING IT SO LOUDLY"
Imagine that in a Stephen A voice and I would think it's pretty accurate.
It would be a great pickup though.
