Does anyone know how involved Mangurian was with game planning, scouting, etc.? Because based on our consistently under achieving tight ends, I don't see this as a huge loss. If he was involved in many other facets of the daily operations, maybe this is, but I think tight end play could be improved under a new assistant.
The underperformance of the tight ends is a lot of talk and not a lot of substance. They've underperformed as receivers, but have consistently been great blockers.
When you have Randy Moss and Wes Welker, the blocking is much more important.
