Gabe could run particular routes sure, but in 8 games he had 2 catches or less. That's not handling volume. Diggs is everything you've said but something broke and he lost his, want to, for this team. His volume faded as the numbers prove that out.
I won't go so far as to say, we're definitely better, at WR but I think we are. We've addressed the position and there's a lot of, let's see. It's a wildly different approach/group for sure.
Shakir and Kincaid provided volume last year, which was an issue, not a strength.
