No, i think Fitch is a better opponent for Penn.
1. Both Fitch and Shields would go for the takedown and proberly get it.
- If not Fitch would at least be able to try to strike(avoiding another Maia vs. Silva type og fight).
2. Both Fitch and Shields are grinders, but Shields has more grappeling experience and would probarly neutralise BJ's JJ.
While Fich will be put more to the test.
I train grappeling and love the grappeling aspect of mma, but i agree its boring when a guy wins just because he's on top. But "Hate the game not the player". I think that if Top/Bottom possision and takedowns didn't count on the scorecards you would get more exiting fights.
