IMO at this point the UT coaches should not be looking to take ANY other position players except on the OL. They lose Jackson, they need to use the spot for an OL guy. They lose a CB, another OL guy. Unless of course they can only take the 24 mentioned in which case they have to trim (2) anyways.
With having (4) committed it could prove to be a tough sell to get more OL commits, but I think they have to try. With most of all the current UT OL being back next year, it will be tough for anyone to come in and play right away IMO.
