It's a no brainer.
IF he's healthy, it's a great addition and a need.
Miami has the potential to be vastly improved in the defensive secondary this year. Maxwell, Hall and Howard are big time better than Grimes, McCain and Taylor. Even Lippett will contribute this year, imo -- Lippett isn't overly fast, but he's got great football IQ.
You improve the DBs like this. And add in a healthy Kiko to MLB, keep Jones healthy at S, and suddenly Miami looks way better up the middle and on boundaries. Vertical thirds aren't gonna give WRs huge separation windows and automatic completions for every ball just thrown up there, like last year, many times.
Pick up Hall if he's healthy.
