He definitely did seem kind of off, very low volume and just couldn't get out of first gear at times.
That being said for all his physical tools and talent he is a head-hunter with limited weapons - there is so much tape on Neil Magny that the blueprint is there. Kick his legs, attack his body, don't go into the clinch with him, and put volume + a pace on him.
What did Geoff do? Mostly follow instead of cut off the cage, throw nothing but 1-2's with power to the head (no kicks or body work), and repeatedly clinch against the cage.
Hopefully he can get his body right because he's a fun action fighter but if you don't give him guys that will exchange power strikes or come at him with heat he ends up chasing and becoming predictable. Lucky for him WW doesn't have too many technical out-fighters, but he's 0-2 against that style so it's clearly a big problem for his style.
