UPDATE JUNE 10, 12:19 p.m.: Apparently, the 72-hour window we keep talking about is not a ticking stopwatch, but an actual "three day window" that requires three full days. Does that make any sense? Man, the CBA is a damn mess.
That tweet explains why the Mavericks haven't submitted the offer sheet yet -- it doesn't matter one way or the other as long as they submit it by 5 p.m. tonight. Until then, they're talking sign-and-trade and keeping their options open. At least, that's what I think is happening.
I'll let someone smart than me try and figure this out. Sign-and-trade rumors make it seem more likely Parsons will be a Maverick, but it'll be interesting to see at what cost.
On the other hand, maybe Houston is just cleverly stalling so they can wait out LeBron James and have more time to get Chris Bosh if he becomes available.
