you could play marion at the 4, marion would be a bass replacement, no reason why you couldn't bring back jeff, i prefer marion to bass, his an ideal guy to match on star forwards such as lebron and durrant, when they go small which was done frequently in the finals. It lifts a load off paul.
btw dollar wise it's close marion is on the books for 8.4 and 9 mill next two season while bass will want something like 6.5 and 7.0 mill next two years, i rather pay that extra 4 mill next two years for marion as bass is a free agent and most likely wanting a 3 or 4 year deal for even more money
