The NBA trading deadline rarely has been a period of tumult during the Miami Heat's Big Three era.

Unless, of course, you choose to count last February's luxury-tax dump of center Dexter Pittman on the Memphis Grizzlies.

Instead, Pat Riley has reserved the biggest of moves for when the balls no longer are bouncing, the offseason additions of Ray Allen, Shane Battier, Greg Oden and Michael Beasley, as well as last summer's amnesty release of Mike Miller.

But Thursday's 3 p.m. deadline still tends to hover in the locker rooms of even the NBA's most stable franchises.

"Every team is different," forward Shane Battier said, with the Heat's primary focus on Thursday's nationally televised game against the Oklahoma City Thunder at Chesapeake Energy Arena. "I've been on teams where everybody's been on high alert, 'This could be it.' And you're looking at moving your family and everything that goes along with a trade. I've been on other teams where it hasn't been an issue.
