Don't think of WRs as #1, #2, #3. They are position players.
AB is X, and we have the best X in the league.
JuJu is Y (slot), and we have the most dangerous slot threat in the league.
Washington in is the Z.
In 10 games (5 Starts) he has 8 rec (25 targets) 77yds and 1 TD. That is piss ******* poor for a Z receiver. Z receivers are supposed to spread the field, make downfield receptions, and pull bracket coverage away from AB, and extend drives on 3rd down. They usually average around 15-20yds a catch. His average is 7.7. That's slot receiver average for an edge receiver. It is so below the line, he can't even sniff it.
Hunter isn't doing any better. 4 games 10 targets 3 receptions 21yds 0TDs 7.0 average.
Compare it to last year's Z:
Bryant/ 15games 8 starts (84 targets) 50rec 804yds 12.1ave, 3 TDs. This was a down year from Bryant, and I'd be ecstatic if we had similar production this year from Wash.
Here's a look at a productive Z in Bryant's previous years.
2015 11 games 5 starts 92 targets 50rec 755yds 15.3ave 6 TDs
2014 10 game 3 stars 48 targets 26rec 549yds 21.1ave 8 TDs
In 2016 we had a platoon at the Z
Sammie Coates 14 games 5 starts 21rec 435yds 20.7ave 2 TDs
Colbi Hamilton 11 games 8 starts 17rec 234yds 12.8ave 2 TDs
Colbi's the worst Z of the bunch and is still tripling the pace of Washington's productivity.
People rip Sweed at the Z, and really he was only the Z in 4WR sets, but even his numbers are better than Wash:
11 games 0 starts 10 targets 6 rec 64yds 10.7av
Sweed's numbers are comparable, but he had 60% less targets and no game starts.
I don't know what's wrong with Washington, he has the tools to be productive this year. But to realize he is a problem, you have to understand how the Steelers utilize the Z, and recognize the production they expect out of that position.
