Not only have they been awful at drafting o-linemen, but the previous two regimes under Philbin and Gase favored athletic, finesse-style linemen to fit their quick throw, short pass based finesse offenses. Neither Philbin nor Gase wanted tough, physical, old-school road-grader type linemen, and the result was that Miami's o-line was consistently pushed around and dominated by tough, physical d-lines. In fact, even average d-lines slapped them around! This is why after Gase was fired I said that the ENTIRE o-line should be replaced... including Tunsil. I saw him pushed backward many times; I assume that he wasn't very strong. IMO, he only looked good because the rest of the line was so bad. The only reason Tunsil didn't give up a lot of sacks is because the other 4 linemen were so bad that the guys they were blocking made it to the QB before Tunsil's guy.
When hired, Flores said that he wanted a tough, physical team and a good running game. I realize that it's only Year 1 of the rebuild, but so far the only improvements on the offense have been Parker, Williams, and Gesicki; they still need an o-line and a running game. Hopefully, the new decision-makers will rebuild that line with tough, physically-dominating players, and not the finesse ballerinas brought in by Philbin, Gase, and Tannenbaum!
