Columbia OL With Deep Program Ties, But Limited Game-Action Track Record
Callahan is a Columbia offensive-line prospect to watch for fit and toughness, but public roster data shows limited recent on-field production, so his value is more about developmental upside than proven college dominance. The key differentiator is versatility and football continuity around the Callahan name at Columbia, which can matter in a locker room and meeting room, but there is not enough current statistical evidence to call him an immediate impact starter. If you need an under-the-radar lineman with room to grow, he’s worth a look; if you need a finished product, the résumé is thinner than ideal.
