I wouldn't say the D was great, but just looking at Miami's losses. Miami lost 6 with TT active. The D held Buf below their avg twice, and HOU once and 3 of those pts were a FG after the D allowed *0* yards which would have kept HOU below avg. They held SEA within 2 of their avg, ARI 2, GB 4. Not bad for a D with all the injuries.
No, they weren't great and tackling was concerning. But, overall, the D wasn't as bad as some claim.
With one more above avg CB and a renewed pass rush, I don't expect a bad D in '25.
