From tape I see in JUCO, Clink is bigger(taller and stronger), stronger, faster, has a better motor, pretty much a much better player overall, and Combs was pretty good in JUCO tbh. Clinks also faced better competition than Combs. Combs usually got into the backfield by just sliding to his right or left and using his hands to push the guy due to their bad technique, which is good technique on his part, but likely works a lot less at D1, Clink has a lot more strength and speed to get through and around defenders.
