Not enough wrestlers using wrestling. Bader made no serious attempt to take Lyoto down I mean what the ****
Too many guys abandoning what got them there and hiring "boxing" coaches and then suddenly considering themselves strikers. Another good example is Lesnar trying flying knees and no freightrain takedowns once re**** Pat Barry joined Deathclutch. Strikers tend to stick with the sprawl and brawl mentality by contrast.
