Here's an RPO with Power-O, a bubble screen or a go route.
The run is outnumbered, so the choice is bubble screen or go route. The throw is behind Marcus Johnson and forces him to stop, negating any chance the play had of success.
Here are two reasons the go route is better:
- It's basically 3-on-2 on the screen side, but it's clearly 1-on-1 to the single-receiver side. The safety will try to help but he has zero chance of getting there if the throw is outside the numbers.
- The screen depends on Armanti Foreman's ability to block and Marcus Johnson's ability to catch and then not hesitate, all things he's terrible at; the go route depends on 6-foot-2, 184-pound John Burt's ability to outrun, outjump or outmuscle a 6-foot, 170-pound corner.
I don't know why Heard went with the screen except that it's a safer throw. Texas won't beat TCU with safe throws.
