Kerr actualy makes a pretty flawless argument and brings up points that I had never considered.
It's something I've been thinking about recently because I really think this is one of the least talented groups of players in the past 2-3 decades. We're stuck in a time when the best players of the last two decades are getting old, slowing down or retiring (see: Duncan, Kobe and Shaq respectively. The list goes on, too). Really, we only have LeBron, Wade, Rose, Howard and Durant as the real superstars in their prime. Kobe is still a super-star but he's past his prime. You can make a case for Melo, Amare, Deron williams and the likes but let's be honest, they aren't superstars, they're stars for sure but I don't know if they'll be remebered as the very best 10 years from now.
Back in the mid 80's and early 90's you had Bird, Magic, Jordan, Shaq, Barkley, Olajuwon, Payton, Malone, Stockton. Later moving on to Kidd and Iverson. All of those guys can be considered the greatest of all-time at their positions. Right now I think LeBron and Kobe are the only guys in the conversation for All-time greatest players. There are a lot of good players but guys you can mention in the same scentence as Jordan are running pretty low.
Maybe another year or two in college for guys coming into the league wouldn't produce more great basketball players. Honestly though, it can't hurt and could produce another great era of NBA basketball like we saw in the 80s and 90s.
