If the Injuries continue like this year, it's not going to get any better.
Injuries are part of the game, but when it affects the way your offense plays, and the way the defense plays, there is very little a coach can do to help their team to be competitive.
Miami had 5 starting O-Linemen, two starting WR, 2 starting RBs, and their starting QB playing playing hurt or out in their last 5 games...Way to much to overcome when playing top talent.
Same can be said on Defense, with losing their 3 top Pass-Rushers, tgeir starting M-LB, their star safety, and one of their starting Corners.
I said it before, and saying it again, no team can be successful that every year leads the league in overall injuries and out for the season Injuries.
Evaluate what is causing this (Field, Training, Conditioning, practice technique, broken mirrors...), and deal with fixing it already.
