To my knowledge, Nick has only faced Yianni once. The score was 12-7 and wasn't really that close. That said, Nick has done well in the past avenging losses. Not saying he will beat him next time, but wouldn't put it past him.
My guess is Nick fits behind Yianni, Eierman, Meredith, Kevin Jack and Brock Zacherl, which would put him at 6. He'll have to beat McKenna and if not win the Big Ten, finish 2nd to see that high of a seed I would guess. Don't see the others losing before nationals. Heil is the wild card. As BrennanFan said, he's lost 4 of his last 7, including today to Ian Parker of Iowa St. Parker moved up from 133 after Kanen Storr decided to transfer all of a sudden last week. Not sure if he bounces back, where that would put him in the seeding. Also not sure if he wins the B1G if they would seed him above Zacherl. Zacherl won head to head, but will have faced nowhere near the level of competition.
Still has matches against Ohio State, Iowa and Buffalo remaining before conference. Lots of work to do, but is definitely heading in the right direction.
