Dude...how can they be a non-contender the year they win a le?
They were contenders up until 2008, imo. Since 2009 they've been woefully embarrassing in the playoffs--coinciding directly with age, and the loss (or choice to play Finley over) Bowen. Since then they have been a defensive team who gets sodomized in the playoffs.
With Jackson and Leonard they have improved on the perimeter defensively, but they are still swiss cheese on the block. Splitter has a lot of upside, and he's still unpolished b/c Pop plays him so few minutes. Pop's a victim of his own regular season success, and won't adapt to playoff basketball.
