I believe that bringing Levi back is the BEST move we could make along our OL this off-season. He has been asked to do what no other LT has been asked, (to protect as many times a year as we throw the ball, and do it without any help). Other LT's protect as often, but most get help. Levi has been on an Island all along. He has performed better than most under those conditions.
My concern with the FO is not having made arrangements in advance for replacing him with a younger player, (or locking him up long term). After all, he has missed virtually no time playing due to injury, illness etc. It is not like we didn't see this coming. To me, that is simply a no, no for a front office.
