Really tough to predict given I haven't seen much of Jamison at this level in folkstyle, but sounds like he was doing very well in the Minnesota room. AA sounds very possible. 4th could be tough with others like Brock Hardy lurking but certainly not unrealistic.
Alvarez is difficult to predict given his change in weight class or potentially two. Some guys are able to pull that off and others aren't. Talented enough to be in the convo for AA but for me, finalist would be somewhat surprising.
