I love this modern love for "athleticism". It cracks me up. Just because they're more athletic (somewhat questionable, but i'll play along), doesn't mean they'll win.
The original could all shoot, out of the modern team up there ^^, i'd take Kobe, Billups and Pierce as the "shooters". Bird, Stockton and Mullin, not to mention Malone, Jordan, Drexler, Ewing, Barkley could all shoot as well as them, mostly better.
As for Center, Howard Vs Dream Team.....puhlease!! Robinson would school Howard SO BAD!! As would Ewing too.
And as for the "who would guard LeBron?" talk, I'll think you'll find that a certain awesome defensive player on the original Dream Team (should read, only Dream Team), while not as strong as LeBron, was smart, quick, long and had great hands, and was one of the best defensive players at his (and LBJ's) position ever, would do a very good job on him, with some help from his running mate MJ, would be none other than.....Scottie Pippen!! But you young ones wouldn't know about that, because he can't grab a penny off the top of the backboard.
Athleicism - making sport more boring for more than a decade! Just ask the AFL.
