There was no 2nd year leap for Olave.
Statistically, whether you go by plain old stats or PFF ratings, Olave was pretty much the same guy in year 2 he was during his rookie season. Now, I don't mean to say that's a bad thing, it underscores that he appears to have been a high floor receiver, something this team needed when they moved up to draft him.
It's just that, realistically how much room does he have for more growth?
It's not like he wasn't the #1 WR already last year. He led the team in targets by landslide, and there's a quote of Carr mentioning the team was already positioning him as the #1 guy with Thomas still in the building.
For now, I see a guy who's put up #2 WR production with #1 WR targets and that was with health luck mostly on his side. Year 3 is either going to be an explosion or step back.
