So we’ve mentioned a time or two how the Bishop McGuinness offensive line could be really good this season. For us, it starts with senior left tackle Jacob Costello Jacob Costello 6'5" | OL Bishop McGuinness | 2026 State OK and he’s one of the more underrated prospects in the state. We got a great chance to watch him go to work back in the spring at a team camp and he was dominant. The Irish have several guys to look out for on the offensive line but Costello checks a lot of boxes from a prospect perspective. He’s listed at 6’5 and over 300 pounds and he simply made it look easy when we saw him back in the spring. We think that he has the potential to set the tone for the Irish on the offensive line and have a big year.
