Realistically you'd like your guys to reach 50 defense, other coaches will have a lot better but in your first couple years and with eh prestige it'll be hard to get those top tier recruits consistently. So I'd say that even assuming some of your guys have high-low potential in defense they'll struggle a little, but thats something you can fix just keep recruiting good defensive players in the future and it will even out. 

Your forwards are not nearly athletic enough to compete against the good teams, you'd like to see them at 60+ and again if they're not high-high potential i don't see them getting there. 

Your guards could be more athletic for sure but their speed may make up for it, especially if they all have some room to grow, but all 3 were decently solid in per,bh, and p for freshman assuming they still have some room to grow.

Really solid stamina for freshman between the five also.

Overall I think you'll do fine with this class especially since you'll probably have a better class next year with FSS, I would just really focus on bringing in guys who will be 50+ defenders when they'er seniors.
