Not sure why Iowa considers themselves "Tight End U"...... There are several schools who have put more tight ends, and better tight ends in the NFL than Iowa. Miami and Notre Dame easily come to mind.
The best tight end Notre Dame has had drafted in the last 30+ years is Kyle Rudolph who has never been considered a top 10 caliber TE in the pros.
Since 2000 Miami has had 12 TE's drafted and Iowa and Notre Dame have each had 11 drafted.
I would rank Miami first followed by Iowa with Notre Dame a distant third.
