SD MFN-7
Approximate Tackles - 220
Approximate Missed tackles - 50
Is the ratio too high? Too low? (This also doesn't take into account where a missed tackled slowed up a runner who was then tackled shortly thereafter.)
Maybe the key is loading up on guys who can tackle. Or putting them in a position, i.e., the proper defense, to make a tackle. Or resting players enough. Lot of variables to consider.
