Horribly mainly because he got all foldens backers. The ones he has recruited were not Miami caliber. BTW, I wonder if Manny would've done any staff changes if the fan base wasn't so bent out of shape this year.
Most glaring problems are cb and wr imo. If Manny wants to put his good name on the line with unprepared and unproven players at those positions. The starters at those positions are too topsy-turvy to play at Miami.
