Every body added this cycle increases the chance that Hegarty and/or Hanratty doesn't come back. As a rule it probably doesn't make sense to bring in a guy to redshirt at the cost of bumping a fifth-year o-lineman who would be in the two-deep. Hanratty is probably already bumped.
Down the road Tillery and/or Tiassum could switch to o-line.
There are tons of guys who will be redshirt freshmen and redshirt sophomores next year.
I'm fine with just two o-linemen.
We'll see how the numbers play out this year. I have a feeling the staff is planning on a medical scholarship that we don't already know about (meaning not Baratti, although it would be great if somehow he could come back).
