Participate in our Power Lunch chats Monday-Friday at 11 a.m. at NewsOK.com/sports On how much blame coach Scott Brooks should get after OKC's Game 4 loss to the Mavericks: Some, but not as much as people no doubt will heap on him. Where was Cook is the biggest question. But as far as running plays, getting to the basket late in the game, making wise decisions, that stuff ultimately is up to the players. OKC absolutely froze last night. Forget "deer in the headlights." They were hit by a mack truck. The Thunder had no chance in overtime due to the shock value alone. It's no fun trying to coach a team that's in a self-induced coma. On what went wrong with Kevin Durant's last-second shot in the fourth quarter of Game 4: Presumably, it was a pick-and-roll with Westbrook rather than a center so if they doubled Durant, Westbrook would be wide open. Well, Westbrook's screen was pitiful and you wound up with three or four people within about five feet of each other, which made defense extremely easy at that point and Marion stuffed Durant. On whether the Thunder will be better off in the long run after the Game 4 loss: Absolutely not. There only silver lining is there is a tomorrow. Last night did not end the season. It might not even be the Thunder's last home game. OKC has a chance to safe face. On what Russell Westbrook needs to improve in the offseason: Get rid of the selective tunnel vision. We know Westbrook can find teammates. He has too many assists for that not to be true. But he needs to look for teammates even longer rather than wearing blinders while Durant is waving his arms for a wide-open 3 on the left wing -- which happened in the first half last night. Durant wasn't happy. The guy hasn't been open much against the Mavs, so you had best find him when he is. On who's improved most for OKC in the playoffs: [Kevin] Durant. Had a lousy playoff last season. Has answered the bell this year -- not every game, but most. After him, probably Collison, but that stems from simply having more opportunity. After him, Harden, but still needs to be more consistent. On the biggest reason the Thunder struggles in late-game situations: Lack of composure, which comes from lack of spacing, which comes from being too predictable. Mix it up in the closing sequences. I say run a last-second ally-oop down the baseline for Harden. If he misses the dunk, he'll draw a foul. Have a play to get Collison's guy to leave and double-team, then dump the ball into Collison, who no doubt will go up strong. Hit a cutting Sefolosha toward the basket. How about Serge Ibaka on a 17-footer off a back screen? Mix it up. Who cares who wins the game for you as long as you win it? Give it a shot.
