Dependent on schedule, health, Zach and Team's improvement. I would even argue it's not a dependent variable, but a by product.

Look, what your SOS did for Zach is it leveled the playing field for him, even slanted it in his/BYU's favor. Against your traditional schedule the playing field wasn't level and was slanted against him. This masked his talent for even the trained eye. Andre Ware and some still saw it. I saw it (untrained eye) when as a freshman he fit a 15-20 yard pass into Bushman down the sideline with Cody Barton draped all over him in coverage.

The problem is Zach came out of those games with stats that weren't attention grabbing. It took a dumbed down 2020 schedule and related arcade stats to grab everyone's attention and moonshot his draft status, but did he really get exponentially better? I think he got better, but the only variable that changed exponentially was SOS.

Question is, where would Zach's draft stock be without that schedule and what other individual talent is being masked by the team talent gap you play with against your indy schedule. I think Zach would have been a first round talent taken in later rounds similar to Fred Warner.
