Boozer drew double-teams against 80% of the league, just not the Lakers which is what everyone rememers.
Yeah Jefferson did average 23 pts but he was the #1 option and took 20 shots per game that year to do it. FWIW Boozer average 14 shots per game last year, and his FG%'s were routinely 5-6 percentage pts higher than Jefferson, who's range only extends out to about 12 feet.
Look, in leiu of how this offseason has gone, I really like this Jefferson deal and he'll allow us to once again compete for a top-5 seed, but the idea that he's a superior player to Boozer is another case of hometown fans overvalueing opposing players while undervalueing their own.
