Well why are you criticizing Rivers and praising Marshall when Marshall has been the worst lottery pick by a mile, has worse numbers, and was sent to the D League?
Because they have had different roster situations. Playing time for both hasn't been dictated by skill on the court, it's been dictated by Marshall being the 4th guard on the depth chart, and Rivers being the 2/3 guard on the depth chart.
Gordon's healthy, we keep Jack, and Rivers is the 4th guard on our roster, I promise you he's in the D-league by this point in the season. And if not, should be.
