I looked around on
@navery12 link and if I did my query correctly, Jackson was on the floor without either Cole or Gaffney for ~50 total possessions in the entire season.
Now that's not to say he didn't bring the ball up the court at times with either Cole or Gaffney on the game, but my main point here is that he can be used as a change of pace on occasion but just because he may have the best individual passing skill on the team it doesn't necessarily warranted extended minutes as the primary ball handler to facilitate the offense.
