2020 numbers should be taken with a grain of salt, but BYU was the more talented team for the first time since probably 2015.
What does that mean for 2021? I think on paper Utah is the more talented team again, but it should be closer (think 2013, 2014, 2016) and less like 2017-2019.
BYU absolutely can win that game but it is a toss-up at best. A lot will depend on how quickly Utah's offense can come together and who ends up winning the QB derby for BYU. Hopefully both team stay relatively injury free and we can get another classic BYU/Utah finish.
