Not really in 2017 he had a a higher y/c, scored at at a rate of a TD per 11 targets, had a better yac per reception, while playing 56 snaps (132 for the season) the final 4 games had 188 yards (203 for the season), this year at 282 total snaps played; he had 268 yards.
2017--y/c 15.6, 22 targets 2 TD, 11.5 yac/rec
2018--y/c 12.8, 34 targets 2 TD, 6.8 yac/rec
I'm not saying the guys a bum but I don't see anything here that would suggest he gets better ever year. Everything across the board was worse even the amount of 20+ yard receptions went from 3 to 2.
