Gotta weigh in here.Another HOF RC by Scobes! Those Raider o-lines of the late 60s and 70s are the one line that are in contention for the greatet Offensive line ever with those dominant Cowboy lines of the early-mid 90s. That is a tough call.
THe Raiders had three HOFers on their line with Shell, Upshaw and Otto and the Cowboys surprisingly only have 1 in Larry Allen. Both lines were very physical and would blow people off the ball. I might give the Cowboys the edge overall and the Raiders the edge for star power. Either way these two lines are numbers 1 and 1A in my book.
Sadly another connection between those two O lines is 2 of the 4 Hall of Famers died quite recently with Larry Allen and Jim Otto. Allen may be the strongest man in NFL history and after reading the appalling injuries Otto played through and never missing a game in 14 or 15 season, I declare him the toughest.
The Dolphins O-Line of the '70s had Jim Langer HOF, Larry Little HOF, Bob Kuechenberg should be HOF, Norm Evans 2x Pro Bowler. Blocking for the first ever tandem of RBs to each gain 1000 yds in a season.
