These changes have made pas- catching running backs a must. They have made the tight end a massively important position. And they have deemphasized the importance of field-stretching wideouts and pass protecting offensive linemen.
Defensively, these changes have made linebacking corps the most important units on the field. If teams are attacking the 3-5 yard area on the field on quick drops, it is fairly obvious that the players in that part of the field are the key. Defensive interior lines don't matter much so long as they are competent. Defensive ends are somewhat valuable, but the key is to be quick and tough in the middle.
Mike Tannenbaum missed the memo- all of the memos, really. He doesn't value linebackers. He doesn't value tight ends. He doesn't seem to understand that over investing in interior d-linemen who watch helplessly as the other team attacks the flats and the edges makes no sense. And he certainly doesn't get that tying up 30% of our salary structure on offense and on defense in the lines was trying a 90's mentality in the new millennium.
The Dolphins suck because they are built to play a sport that no one else in the NFL is still trying to play. The contracts suck. The concepts suck. And the general manager, unless he is secretly working for the Kraft family, is a complete wreck. Let's blow it up and start over.
