College football is in the second year of having an early signing period, which will begin this year on December 19 and run through December 21. Last year, we learned that basically anyone who is (a) committed prior to the early signing period and (b) does not sign a Letter of Intent during the early signing period, is probably going elsewhere.
On the other hand, last year all but two of Vanderbilt’s commitments at that time did, in fact, sign early. Miles Jones didn’t sign, and ended up at Nebraska, while Rayshad Williams flipped to UCLA literally at his signing ceremony at Whitehaven in February.
