One other caveat as others like
@BonifayRam have posted about the injury history of Sullivan. Now I believe he's past that been a couple years since the back issue and he held up in 8 games with the Redskins last season, but adding Blythe ensures that if something happens during preseason at the very minimum Blythe has had some seasoning in the NFL, but again I feel good about Sully and whoever Kromer and the rest of the staff move forward with come September Morn.
