In my opinion, the Cowboy OL was truly elite under Bill Callahan and hasn't been the same since he left. Pollack failed to get his unit to match previous success and was let go in just 2 season, the hiring of Paul Alexander was an utter disaster. Columbo did a better job replacing Alexander, but was let go this offseason as MM wanted to hire his own staff.
I believe Columbo was running more of a man blocking scheme last season compared to Callahan's Zone Blocking Scheme. The biggest benefactor was Collins as he had his best season as a pro. Joe Philbin will bring back the Zone Blocking Scheme, but I have read an old article saying his coaching is more about the fundamentals then the scheme. We heard the same thing from MM regarding the draft, just find us good players and we will scheme around their strengths. This is very refreshing to hear. Let's take a quick look at some of our OL personnel:
-Tyron-it's hard to believe he is only 29 years old. Injuries have taken a toll, but is still a high level blind spot protector in this league. From my own viewpoint, he struggles with edge speed, but if he gets his hands on you, it's game, set, match. He will miss a few starts, but he is still a very good LT in this league.
-Martin-he is also 29 years old, coming off an injury plaque season. Clearly he wasn't right all season and it showed at times. Like Tyron, dealing with back concerns. Even if Martin isn't playing at 100%. he is still better then the majority of Guards in this league.
-Collins-most of us, including myself were scratches our heads when we heard about his extension last season. Boy, were we wrong. Had a tremendous, breakout season, in which he was relatively heathy, which was a big issue for him earlier in his career. He is one of the best RT's in this league and is still getting better.
-Connor Williams-I believe many Cowboy fans don't give him any credit what so ever and believe he is a total bust of a draft pick. First of all, not many rookies are successful plug and play starters, especially learning to play a brand new position. When Connor Williams came in this league, many believe he needs to add more weight to his frame, he did just that after his first season. He clearly was a better player in year 2 and is still developing. Don't be surprised when he beats the competition and starts against this season. Last thing I will say, he isn't a Tackle, there is a reason why they are playing him inside at Guard as he is short armed for the Tackle position.
Is the OL still considered elite? No, but they are still young enough as a group to play at an elite level again. With better coaching, better health and more development it is possible.
