When he wants to be, Bentley Meyer can be the best OH in the gym. The St X core 4 of that team do enough so that the other "holes" aren't important.
And not only did they beat 18 Black in 2, but then beat Academy 18 Adidas. They lost in the finals to C2 17s and played them pretty tough.
The twins are very good, the OH doesn't overpower you but just tools blocks and finds open court.
With Walsh does 18 Black win? Probably, yeah. He's worth two points per set I'd say which makes those tight losses possible wins.
I know not everyone loves Berk as a coach, but his teams undeniably improve each year.
