I would only go with Jarvis over him because he is way too proven of a playmaker to pass up.
I would go with Richardson over Jordan and Mingo. Also, with Richardson the only places he could really produce JJ Watt numbers IMO is a 4-3 or a 1 gap 3-4 D. He does not fit in a 2 gap and it would be a horrible fit IMO. Only one team besides us runs a true 1 gap and that is the Texans.
