It was about 6-8 weeks.Lol, you may want to revisit the timeline on last summer and adding 4 schools last year.
Within the timeframe that poster listed, you had OUT, the Big 12 schools deciding they would jump to PAC, the PAC deciding the would not add, and the Big 12 deciding on 4 G5s to add. All of that without the ticking clock that is the BIG first taking PAC schools, and the Big 12's calculus changing.
Yormark's job is to make sure PAC schools realize the latter part. The point is the Big 12 can wait more than the corner 4 can. They can't wait risk free.
The decisions happened quickly, the build up can be long. There has been a year build up to this.
Slightly different situation.
First, we were trying to solidify our conference and in a position of need, and urgency to protect our membership. The Pac is somewhat in this position but in their case they have members that do not seem to be all together and still looking for an out, like ORWA.
Second, we elevated 4 G5/independent teams. Not brought in other P5 teams. P5 teams need to make sure it is a beneficial move. G5 teams know it is a beneficial move. It is a no brainer for them. Plus, many of the teams we were considering we had quite a bit of knowledge from just a couple years before, when we had already discussed them.
