The main thing is to keep him in the pocket. When he gets out and starts making plays with his feet, that’s when he’s able to complete passes as well due to the defense reacting to him fleeing the pocket and leaving their wrs open. Id probably got a little soft at first. Drop back 6 into coverage, keep him in the pocket and see if he can read a defense and complete a pass. You risk him gaining some confidence if he hits a few but I think blitzing him out of the pocket where he excels is more risky. But I ain’t no coach so I’ll go with whatever they decide
If you play press man, you're play into UF's hands. You NEVER want to get caught with your DBs and LBs running downfield with their back towards Richardson and give him a lane to get into open field. (See his long run vs Utah) You mix up zone coverages and zone blitzes and make him work it down the field while having everyone rally to the ball if he takes off. Richardson is not going to pick apart a zone and work it down the field. He can burn you with his legs or find one on one with a guy like Shorter and throw up a 50/50 ball vs man.
