Podium this year was roughly 205-215. Let’s say they need 200 for 4th.
It might start as good as this if the top 3 have a healthy season and build up.
15 - Davin
18 - Corrigan
27 - Bons
That’s 60 pts and plausible, if unlikely it would all go as hoped. That means two more of the other guys you listed need to score under 140, averaging 70.
It’s a stretch, but it doesn’t seem like an unreasonable goal for Eyestone with all the success he’s having. But while a 70 pt scorer isn’t rare for BYU, it sure isn’t a given that there are two new ones to be found next year.
