See, this is why I disagree. He lost to Ank the first time around. If the road to Jon isn't already over from that loss, I'm not sure why it would be for losing to Tom. Maybe Gane, since Jon tooled Gane, but it's not like Alex had the HW belt the first time Jon wanted to fight him.
Hell, if he gets subbed by Tom, that might actually convince Jon how easy it would be for him to sub Alex. Might even increase his chances of getting it booked. It's not like a belt would be necessary if it's a White House special attraction either.
Even if someone argues that losing a title fight takes Jon off the table, I can't see anyone arguing that losing to Jon keeps the title fight on the table. If both are true, then the whole two fight premise is out the window entirely, in which case I agreed, yeah, go after Jon, but I think it should still be noted in that case that: it's gotta be unanimously agreed that the title fight is much more guaranteed to happen than a Jon fight, which still might not happen at all
