JJ was and is a very natural striker. He's learned the grappling more and more since he came in. Phil is sort of the opposite, natural grappling prodigy. Within a year of starting BJJ he won a world championship( blue belt 221lb+ super HW division). But he just hasn't taken to the striking like JJ has the grappling since then. Just no idea how much to can attribute to natural ability and how much to training. JJ has been with Greg Jackson almost from the start. Love or hate the camp, fighters there are very very well trained. Davis was at Lionheart gym, whatever the fuck that is, and now the Alliance gym started by Brandon Vera. You just have to imagine if he was at Jackson, AKA, or Alpha Male(now that Bang Ludwig is there and seems to be working great) he'd be getting the striking attention he needs.
