The plan was set and we didn't execute.
Don literally takes away the right side dribble so when Dinwiddie drives down to Rudy, he's double teamed on his right side (right handed shooter) with only one option in the corner in Brunson that Royce was not going to leave. I don't know if it's Don's fault or Rudy's fault that Dinwiddie was able to split them. Hell, might be both. Don didn't rush enough for me to close the gap, but the play was there to be made between the both of them.
If Dinwiddie is kept on his left side and unable to kick it out right side, we likely force a shot clock violation.
