Yes. I'd actually say I personally spend more time watching those B teams because I know what I'll be getting with A level teams from SW, M&D, NEMS, Heros etc.
Of course, I'm gonna recruit the girls from the A teams, but we all know who those girls are.
My GREAT recruiting classes are really built by landing a few of those and THEN finding those girls who have submitted letters of interests and studs from B teams that people are sleeping on. I'm not wasting a ton of my time chasing some player who is getting 20 other recruiting calls per week.
