Saw a rating of the portal transfers last year that had Guerrier at 80, Domask 132, and Harmon 165.
When I ran the preseason numbers and comparables, Domask showed likelihood of a very solid contributor and a major conference starter. It's pretty shocking him being rated as low as he was and overlooked by so many, as his metrics were really really good and players with his size, age, and metrics have had a high likelihood of success when transferring up. To Marcus' credit though, he deconstructed and reconstructed his game to one that obliterated even the loftiest of projected ceilings for him.
As for Quincy, metrics suggested Guerrier at the time was a gamble but a low downside one, meaning if you don't get much out of him he can still contribute as a backup but that he also didn't really project as anything more than a decent starter unless he reverted back to early college form which is not something you can bank on as more often than not it doesn't work. It's safe to say he has outperformed expectations.
Justin was the player that metrics really didn't like and projected him as a deep bench player. Even with the slump that has gone on for almost 2 months now, he's still outperformed that.
So, I think a lot of credit needs to go to Underwood here in talent evaluation of transfers. Since the transfer portal era, he's really only had 1 transfer play worse than expected/projected and that was Mayer. That's pretty remarkable. It's safe to say Brad is one of the best evaluators of talent out there. Impressive stuff.
