Preston Williams is actually 6'5" and DeVante Parker is 6'3" - so you got the 6'4" average correct.With Jennings Miami has to have one of the tallest receiving cores in the NFL.
Parker and Williams are like 6’4
Hurns is 6’3
Jennings and Ford are like 6’2
Gesicki is like 6’6
That’s a lot of mismatches in size, strength and athleticism
Jakeem Grant is 5'7" - and he may happily inform you that it's not just all about height. Speed is also part of the equation.
