The Harline/Coats/Pitta era was special. If you need more options then check out the Sarkisian/Chad Lewis era. Maybe BYU's analysts could see if Chad Lewis would be willing to talk to them about this? I bet he could make time considering his office is probably in the same building.
Also, I do realize that not every play works in every offense and we're running a different offense right now, but I have a hard time believing our existing offense couldn't feature TEs more effectively without a huge degree of adaptation. The UofU was able to get he ball to a TE regularly with an offense that wasn't dissimilar to ours.
