I kind of misspoke above, but I won't edit it further. In general, the team rule is probably, "traveling with the team is mandatory," in most cases. The Rockets knew they'd have to cut White some slack. They just want to make sure he's there and on-time for team functions. They don't want to say, "you have to fly," but they could if they wanted to. Again, what I initially said is White should be there day 1 and willing to work with the Rockets. He shouldn't be holding out and demanding special treatment.
As of 8/1/2015: I will not spend a penny on Panini products at any level until they completely change the way they do business. No cases, boxes, packs, or singles.
