I think that it would be in everyone's best interest for Silver to push the age restriction to two years removed from high school if it will avoid this. In my mind, the only thing freshman ineligibility will end up doing is to push high profile HS seniors to go sign overseas. Who's going to sign with a school and feasibly impact their draft status by not playing for a full year if they have an opportunity to get paid to play overseas? Furthermore, what school would spend all the time and effort(and money if you're Cal) recruiting a player that will most likely end up going pro after not even having played a game for you?
From the NBA's vantage point, they'd still be getting their hands on most players after one year if all this happened, but pulling guys from overseas can get really tricky and downright messy at times too. Of course, I guess that forcing guys to play two years in college could drive some of this behavior as well, but I think it would be the lesser of the evils.
Bottom line, whatever they decide to do about the age limit, it's not the thing that has destroyed college basketball. The thing that has killed it has been the AAU/shoe companies/Calipari model. I've gotta give the man credit... He was essentially the architect of a model that coaches across the country are exploiting today, but that doesn't make him any less of a piece of ****. He's like the guy that became a millionaire by selling weapons to underdeveloped countries but then when asked about the mass genocide of those areas, he says that he's never fired a single bullet
