Participate in our Power Lunch chats Monday-Friday at 11 a.m. at NewsOK.com/sports On forward Kevin Durant's 33 points against the Miami Heat: Sunday was a big step in Durant's evolution. He showed up on the big stage and had success against the Heat in most all facets. His 2-for-10 shooting in the second half wasn't encouraging. But he got to the free throw line 19 times and never backed down against a big, bad Miami team. On the new "rivalry" between the Thunder and Heat: [It's] all hype. They play each other twice a season. And rivalries are born in playoff basketball, not the regular season. So if these two teams were to meet in June and tempers flare and it's a physical series, then, yes, we'd be closer to considering this a rivalry. As of today, after one game, it's extremely premature. On guard Daequan Cook playing more in the second half of the season: I expect Thabo Sefolosha to return for Wednesday's game against the Hornets. If that happens, Cook will go back to being the third shooting guard in the rotation. And it's hard to play three. Almost unwise. So regular minutes will be a stretch. But I think his last two games have instilled more confidence in Scott Brooks to go to him in certain situations, especially if Sefolosha or James Harden aren't producing. On forward Serge Ibaka playing less minutes the last two games: Scott Brooks explained it Sunday by saying Ibaka didn't show up ready to play. Said he wasn't focused from the start. I didn't see anything that suggests that. But I'll give Brooks the benefit of the doubt. I figure Brooks would know better than anyone. Miami also played LeBron James at power forward a bit, so Brooks had to match up there as well. But I don't think this is something that should linger. It's only two games. I expect Ibaka to be right back in there for 25 to 30 minutes against the Hornets. If not, ring the alarm.
