To me, how you judge a defense is really simple. Take the number of times the other team touches the ball, and see how many times you stopped them, how many times you allowed a field goal, and how many times you scored a touchdown.
Forget about total points allowed, and forget about yards allowed. Yards don't win a football game, and points allowed depends a lot on if your offense can stay on the field, time of posession, that kind of ****.
So if you just look at the number of times the other team has the ball per game, and how many times they score, and you adjust it to reward you more for stopping good offenses and penalize you more for letting terrible offenses score on you, how does Miami stack up?
We suck.
Footballoutsiders.com has a stat that measures that very thing, called the FEI index for anyone that's interested. Apparently, Miami's defense is ranked #82 in the country. We are THE WORST team defense in the country out of every big name team except for Tennessee, Texas A&M, Colorado and Arkansas.
Some examples of teams that objectively have better defenses than Miami:
Cincinnati
Maryland
Rutgers
Buffalo
Rice
South Alabama
Colorado State
Texas State
Marshall
Middle Tennessee
Toledo
UTSA (hello Larry Coker)
Ball State
Duke
Tulane
Tulsa
Wake Forest
Memphis
North Texas
Northwestern
East Carolina
Utah
Utah State
This is unacceptable at Miami, and I have never seen a more clear-cut case where a defensive coordinator needs to be shown the door at the end of the season. It's not personal, but we need to go a different direction, that's how it is.
Something to think about.
