I mean Rhodes vs Spears is basically a combination of Rhodes vs Rhodes and Rhodes vs Allin - Cody has a long history with Spears going back to OVW days when Cody was first signed as a 20 yr old and they tag teamed together and has the Darby aspect in that Spears needs to prove himself against Cody.
Another time limit match draw can't happen. So I assume it will be close to a draw, but have Cody win like at minute 13 of 15 minute limit or something. You could have Spears go for a big move gamble late in the match desperate for the win and he misses and causes him to lose.
Something else that I'd like to see storylined along the way of this arc is the fake crazy of the Spears character. Sure he can play the out of control badass when facing Cody and MJF - but I'd love to see him punk out facing Moxley or even Janela. Fake crazy meets real crazy sorta deal and realizes they're in deep shit. Not everybody can be a bad ass, especially it being out of character for what we know of WWE Spears and I think it would be an interesting character layer.
Sure this is AEW, but they play off the Spears WWE run and will play off his history with Cody so he's not a new character he's portraying, but rather the former Tye Dillinger, the Perfect 10 guy, from WWE.
