Like I said, unless a spot is legitimately up for wrestleoffs, I don't see Cael allowing teammate matches to happen.
Last year
Lilledahl vs McHenry - wrestleoff (obviously the spot was going to be Luke's but you make a true freshman wrestleoff)
Kasak vs Facundo - wrestleoff
Levi vs Matt Lee - obviously Haines had the spot, no match
Starocci vs Ryder - obviously Carter had the spot, no match
Barr vs Connor Mirasola, Barr vs Cochran - wrestleoff
Kerkvliet vs Cole Mirasola - obviously Kerkvliet had the spot, no match
I can see Duke and Sealey match being allowed to happen (for same reason as Lilledahl, a true freshman should wrestleoff) and definitely Cochran vs Cole Mirasola. If Marcus has a PSU guy in his path then I'm sure they'll wrestle.
Barr being injured ironically allows Cael to punt a decision on what to do with 197. If hypothetically he was available, it would be a tough decision to handle. On one hand, a previous finalist earned his spot you'd think. On the other, the other kid is a major blue chipper who just majored a Top 8 guy and has done everything right, is all in on the program and should get a chance.
