i understand and agree to a point that cohesion and continuity is important on an o-line, but true talent; speed, strength, coordination and toughness, can overcome a lack of continuity. If these guys are better than they were or better than their predecessors then it will become obvious quickly.
A good coaching staff will also know where they are in terms of that continuity and plan accordingly.
Even though it was in a completely different program the practice time that Calahan got against that defense and the playing time he got will make it a lot easier for him to adjust and contribute. The decision on his eligibility is a huge one for us.
