CP has a better plan.
I thought it odd too that they'd be wrestling off so late in the season but at the same time, they presumably wrestled off early in the season and Rasheed has looked much better since his first tournament and injury. A wrestle-off now would be useful to compare against the result of the first wrestle-off to see how far along Rasheed has come vs how much his success has been just a great cradle. Ben Darmastadt could've served the same purpose but he was probably unavailable.
As for criticizing Cael for Rasheed getting injured in a wrestle-off, insert eyeroll emoji here. Guys get injured in practice, they're not porcelain figurines. Weak Monday-morning quarterbacking.
