This is really bad for Walton. He's probably the best pure TB in the ACC and I was looking forward to us containing him (again; you can check) this year. Here's hoping he gets well and gets his full function back. He'll be a late first round draft choices if he does. I don't think his absence will hurt them that much, however; they have good depth at TB.
And, as a general principle, I want Tech to play other teams when both sides are at full strength. If you're 100% and so are they, there are no excuses and you get to see how good you really are.
