No way does Brook's shirt get pulled if Shak is still healthy, and Conel the go to at 197. I don't see how anyone can't see this as other than Conel's days as the starter at 197 are winding down. Shak will be our starter at 197 mid-January and I suspect Cael thought it better to give Aaron some December reps than wait for the two-fer lineup change next month.
Cael knows full well how long it takes to get back to AA I form, and despite some improvement Conel is a long way off (if ever) to recapturing the lightning be in a bottle March that is now over 20 months in the rear view mirror.
I suspect the toughest part of the decision was which shirt to pull, and after yesterday I am 1000% convinced.
