Even if his 13:06 was worth a 12:48, which it certainly is not, he wouldn't be a global threat.
We have to shift our perspective on times, for two reasons: the general level is higher and the shoes help a lot.
There are 3-5 guys who will be in 12:3x shape for the World Championship 5k (Cheptegei, Kiplimo, Jakob, Barega, and potentially one of the other Ethiopians). That's the fitness it will take to win a medal. There are 3-5 guys who will be in 12:4x-to 12:55 shape for the US Championship 5k (Chelimo, Woody, Fisher, and any number of the other Bowerman guys if they get back to form). That's the fitness it will take to make a team.
Can Teare break 13 this year? For sure. Can he make a U.S. team? Maybe. Will he get blasted at Worlds if he does? For sure.
I'm not bashing him, either. Give him a couple years and he might be in the conversation. Look at how far Grant Fisher has come.
Elite times have not improved since the shoes arrived. So no adjustments to make.
