That's the part I couldn't understand. Two years okay... but three? I never even considered the MLE angle.
I wondered if it meant they consider him a full-on project, that they are willing to commit to. I know the way they signed him before the showcase looked like they were afraid someone else would pick him up. But, like I said, it probably doesn't pay to read too much into ANY D-League callup.
I saw a reference to the 3 years earlier in the week, but wrote it off (sorry, can't remember where). I saw it again on RealGM this morning. Nothing to say two sources can't be mistaken, but it made me wonder.
