If someone can go through a cadence and snap the ball about 3 times a minute (1 snap every 20 seconds on average), that means he can do about 180 practice snaps in an hour. If T.J. Bass were to dedicate himself to one-hour each day practicing snapping the ball, including his off days, he could get in about 1260 snaps a week. At that pace, it would take him about 8 weeks to obtain the muscle memory required to become competent to be the Cowboys backup center.
The Cowboys are going to play 6 games over the next two months, leading up to their 7th game against the LA Rams on October 29th, which occurs after the bye week. With two centers on the practice squad, the Cowboys can activate each practice squad center 3 times each to get through the first 6 games. After that time, if Bass puts the work in, he could become the backup center on the team for the final 11 games of the season, plus any playoffs. Of course, Bass would need to continue practicing at center to gain even more experience in practice during the season. But it is possible to create a realistic plan for Bass to become the Cowboys’ primary back-up center by the end of October.
I cannot verify that this will be the plan of the Cowboys, but just running the numbers, this plan makes sense to me. We’ll see if he becomes trusted to be the backup center after October.
