I agree, in general with what you're saying. Sitkowski has potential to be very good.The issue with him in high school was he played at Old Bridge. Their offense is not suited to what he could do. They did not have the kids to run a spread passing offense. I thought he played well down in Florida but had to split time on an elite level team.
He has all the tools to be an elite QB. Our issue last year was inexperience at QB and inexperience at WR. No one could make a big play because they were all still learning everything.
I think this year is going to be a big tell on how they all develop.
I think the problems last season, in addition to what you mentioned (underlined above) include that the O line was non-functional against good competition and very inconsistent even against bad competition. Combine a porous O line with WRs that struggled to get separation and it's a going to be a rough day for any QB, no matter how good.
I don't really know what to expect from the O line this season. I have low expectations for our WRs because, from what I've seen around the NCAA, truly great WRs are usually pretty good right from the start and just get better over time. I didn't see much "pretty good" from our WRs last season. Maybe it was coaching?
