I gotta tell ya, playing Alvin Robertson at PG is a mistake. Has no range and he wasn't a very good playmaker (even for a shooting guard).
This matchup is a lot closer than a lot might think. Playing Cowens more to offset the beating Love would take against Timmy? OK, but your team has very little spacing at that point, which is going to be a HUGE issue against that twin-tower-on-roids frontcourt.
To be honest I think Duncan/Chamberlain win this thing.
