area with expensive houses just shows you have no real argument against him.
There is always the question mark if someone will perform at a higher level until they do it, but you can't just discredit 3 years of double digit scoring (increasing his PPG every year) and call that an extremely sparse body of work. Toolson, Khalifa, Waterman, Bryant, Johnson, etc. are all recent players that came from "lower competition" and very much succeeded at BYU.
Add in the factor that you can't teach experience either. He is a player with 3 years of college playing experience, and another year of practice around a good Big 12 team.
Here are some of Baker's 2022-2023 points stats (so the year before transferring to BYU) against teams we are familiar with as BYU fans:
@Santa Clara: 14
Fresno State: 12
@San Diego State: 14 (3 point loss against an SDSU team that went to the national championship that year)
New Mexico State: 19
@Pepperdine: 12
LMU: 19
@Oregon: 11
@Oregon: 16
That is 14.6 PPG in a decent sample size of 8 games (averaged 15.3 PPG, 46.7& FG%, and 36.9% 3P% over the whole year), a PPG total that would have made Baker BYU's leading scorer that same 2022-2023 season.
People can be wrong, and he might not be an amazing player, especially if he can't be healthy, but there is no reason to believe that he can't be a great player for us either.
