When I first noticed that Robinson was guarding Hammons, it was after both Hartman and Holt had picked up too many fouls at whatever point in the game it was. I wondered who was left on the bench to guard Hammons, and lo and behold, it turned out to be Robinson. I was happy to see that Robinson actually took interest in this assignment, shoving back when Hammons pushed him, constantly trying to front Hammons no matter what Hammons did etc.
Robinson ended up with 3 rebounds, 4 points, 2 assists, 0 turnovers, in only 15 minutes, despite a very difficult defensive assignment. I assume you are not criticizing Robinson. If so, he doesn't deserve it.
Robinson's effort to guard Hammons is why he started the second half. Blackmon had several stupid turnovers from ill-advised passes and at least one stupid incident of bad dribbling.
I saw several players on both teams slip on the Mackey Arena floor and wondered if anyone heard anything about condensation, thrown drinks, perspiration etc. creating slippery floor conditions.
