Benavidez was throwing the kitchen sink at Gvozdyk early, thats what gassed him out. I'm sure David will improve, but some of the things he learned about himself are things he can't improve at 175, specifically that his opponents will be much stronger, durable, and physically imposing than he's used to. At 168 David's strategy was to physically overwhelm his opponents with his speed, volume, size, pressure, etc. That won't work at 175, he's gonna have to come up with a whole new game plan.
