He attempted it. He psyched himself out of it. You could tell. I'm sure we'll see it again in France. He'll be fine. He's a hard worker, whatever anyone may think, and he's actually a really pretty good jumper if you take your eyes off the quads for a sec.
"let alone a world team spot"? Who's beating him then? There are three spots, remember. Nathan's a given, you'd think. Vincent? His URs could easily do him in. Alexei? Timothy? Alexander Johnson? Camden? Really? You really think any of those guys are gonna score bigger than a clean Jason, even sans quad?
Everyone's got their eyes on the quad (you better have complained this much about Adam's lack thereof as well). The actual, telling, real signal, was the absolute frickin' money 3A-3T. The US haven't seen one like that since Joshua stopped doing them. That was the signal that when he's less nervous and more comfortable, he's gonna be right as rain.
