Scott Booker coached TE's and to a lesser extent, st in his stint at ND from 2012-2016.
In that time, he coached Tyler Eifert (2012), who led the team in catches/ rec yards/ tds while being an all American, Mackey winner and 1st round pick.
Troy Niklas was next and while most would agree he didn't reach his potential at nd, he was drafted in the 2nd round a year after Eifert.
He followed that up with Ben Koyack, Durham Smythe, Tyler Luatua, Nic Weishar and Alize Mack. Not shabby, and Mack could've been the best of them if not for some mental issues.
He also coached Kyle Brindza, Tyler Newsome and Justin Yoon during that time.
High standards, for what is deemed to be poor, even by IE board standards.... I'm not calling Booker great by any stretch, but his players generally played well, produced and went to the league.
