The Pats have had multiple OLinemen over the years who were starters either from Day One, or fairly early in his Rookie year: Thuney, Mason, Storm, Solder, Vollmer, Mankins, Light, Koppen. In fact, for the most part, a Pats drafted OLinemen either starts by middle of his rookie season and ends up being a long-time starter, or he’s a nothing burger. Cannon (as a late bloomer) and Stork (as a late washout) are about the only notable exceptions.
Looking back thru the years, it seems that there is usually one Year One major contributor, one slow developing later contributor, and one useful role player from each draft
