Well I dig up a little bit of history on the last 3 teams Karl coached before landing in SAC.
Karl coached Sonic's Payton-Kemp-McMillan-Schrempf era, Buck's Casell-Ray-Allen-Big Dog-to-Micheal Redd, and Denver's Lawson-Anthony-Nene time.
Except for the Buck where he got Ray Allen and then Redd, Karl never made a scorer out of his SG.
What's consistent though is that he gets his PG play at star levels that's Payton, Sam, Lawson, and now the revived Rondo.
His forwards gets a good share as well, Schrempf, Robinson, Anthony, and now Rudy.
And if he get a good big they'll get nice stats as well Kemp, Nene, now DMC.
However, it's quite his habit that his SG has to challenge his time against Karl's other PG. With again the only exception with the Bucks because Ray Allen and Redd (Allen's backup) are damn legit shooters.
Payton plays with Nate, who is a big PG.
Lawson gets round with Miller, Affalo, and Iggy.
But what we have in SAC is Ben and Belinelli who can't hold a candle to DC.
But DC is not big as Nate McMillan even Dre could guard SG better then DC, IMO.
So in all honesty, Karl got the worst other guard option to field in all his career.
Maybe it's time we get some better SG option. I hope it's not too late.
