If he hadn't broken it, then that would have meant that we would have lost more games along the way.
It should have been broken earlier, but his stubbornness to adapt and his blind loyalty to some cancers on the staff and roster delayed it.
To put it this way, I would guess that there were at least 12 wins left on the table from 2014 through 2016, thanks to the incompetence of Brian Van Gorder, and to a slightly lesser degree, the shitty strength and conditioning program that Paul Longo had in place.
