Poor Nick Kaczur, the kid can't catch a break here. Does anyone recall where the team was when he was drafted #100 overall? Yep, just off winning three Super Bowls in four years with Brandon Gorin and Tom Ashworth and similar RTs developed in the Scarnecchia laboratory. NE drafted a LT at the end of Day One which prompted a few cuss words in draft war rooms around the league as they lost out to NE, again (there were articles to that point).
It's always interesting to read the discussions talking about moving Light to RT and pushing Kaczur down the roster. Many of the complaints fans have about Kaczur have been applied to Light for the past eight years, and any that have died down would resurface rapidly as Light struggles to overcome the muscle memory of a career LT. Light and Kaczur are bookends, similar players in many respects, and players who have started all but a few games in their Pro careers. This would seem to indicate a couple things, to me at least: 1. Scarnecchia trusts them to play at a consistent NFL starter's level and execute the blocking scheme correctly; 2. Scarnecchia and Belichick trust them with the Franchise (it's not as if Brady suddenly became valuable in the last couple years, he had proven his worth by the time Kaczur was drafted and Light was extended).
What do we know about Beatty, Oher, and Britton? We know two of the three (Beatty & Oher) are inconsistent performers, long term starters who don't bring their "A" game every down. That right there is enough to question them as first round picks for NE. The second caution flag for both Beatty and Oher is passion, both appear to be nice young men, neither has been painted with that onfield application of "nasty" so desired by Scarnecchia and other top OL coaches. Of the three Tackles being discussed, Britton is the more consistent and the one closest in nature to Scarnecchia's "nasty." If people truly believe it's time to replace Kaczur, Britton is the more promising prospect.
Myself, I don't see Coach Belichick spending the high round pick to replace what he currently has with Light and Kaczur. I think it's more likely he drafts another 3-4 year starter later in the draft, and lets them battle it out with O'Callaghan, Britt, and LeVoir. With a draft class as deep as this one, I can see him picking up another good kid in the late rounds or as a UDFA to groom on the Practice Squad, and if he doesn't do it around draft time, he'll grab someone off waivers after final cutdown.
