So it appears only four Hokies received invites to the NFL Combine this year:

These are the four

My question to you is of the other Seniors from this years squad, who surprises you the most that they did not receive an invite?

Seniors per the roster this season
Trey Gresh
Derrick Hopkins
D.J. Coles
J.R. Collins
Tariq Edwards
Tony Gregory
Andrew Miller
Jack Tyler
Tyrel Wilson

If I had to put my Top Three Snubs out there, I think it would be this:
1) Derrick Hopkins
2) Jack Tyler
3) J.R. Collins

Since it has been asked a few times, I figured I would update it here:
Regardless of an invite to the combine, all of these seniors are eligible to get drafted or sign as free agents in the NFL once the draft has concluded. The combine just gives them a focused opportunity to perform in front of scouts prior to the draft. There are Regional Combines and some players get qualified from those to go to higher level combine activities. They also have the Pro Day that Virginia Tech will hold to impress scouts. I do think that Hopkins and Tyler have a shot at getting drafted. I think Collins, Edwards and Miller are all 7th Round bubble guys, all dependent on what a team needs. All three will likely sign as Free Agents if not drafted. I don't know what I think of Coles chances. He has the physical gifts to play up there but the injury bug may just be too great for it to happen.
