Last year Mangold played with left guard James Carpenter(former first rounder) and right guard Brian Winter(former third rounder) who just got a contract extension for playing well . Neither of those guys are Marshal Yanda but from what I have gathered they aren't terrible either. Winter was bad in 2014 and 2015 but his play was better in 2016 but Mangold has not always played with other great offensive linemen . This is the same guy who has been a top center in The NFl while playing with average starters like Vlad Ducasse , Willie Colon ,and etc. I can understand injuries but beings surrounded by talent hasn't been the reason for his success in the past so why would it be now? . Jeremy Zuttah had his worst season last year as a Raven and for most of the season played through injuries but I don't know why he doesn't get a pass for that .
Blocking scheme wise I don't know The Ravens direction with that . They hired a offensive line coach that has experience with teaching the zone blocking scheme and Marty M likes that scheme . Greg Roman himself has experience using it especially when he had Lesean McCoy as his starting running back when he was The Bills offensive coordinator. Mangold is 33 years old and I have no clue on how good he is even if healthy but I hope Ravens fans aren't showing interest in this guy because of name alone.
