It's easy to blame Hill, but TP and Tim had 3 turnovers between them on consecutive possessions. Then Tim gets a tech and fails to run down on defense. The team as a whole was sloppy and committed a rash of turnovers, thereby allowing the Thunder to get new life and get back into the game. Terrible, terrible execution by a veteran team.
And for the record, I don't need to see any more of the Roer Mason backup PG experiment. He committed his share of stupid turnovers, also. Dribbling off his leg, ill-advised passes and such. Stand down Pop.
