Ding Ding Ding Ding...been saying this, the major diference was never going to be MM using 2 TE's to smash moutht he ball, it is the diference in route scheme's, WCO MM will run is a focus on hot route that wants to create mismatches for that route in coverage 1st read , 2nd read, 3rd read ball comes out or take off but kill the play. KM used option routes 4 wide alot so all 4 WR needed to read the coverage correct and the QB needed to find the open option route while reading it the same as the WR during play.
