Well in my opinion, having 2 receivers make NFL rosters is pretty damn good. How many schools have 2 receivers make NFL rosters? What is your definition of good, 3? Seriously? You still want to argue that we didn't have much talent in Zone 6 even though 2 were deemed NFL roster worthy? We just are not going to agree on that then.

When the only desirable NFL talent is a single all purpose tailback, there's a problem.
Also, I expect a sharp uptick by 2019 (or before) with Mack, Victor, Grimes, Harris, Trey Knox, etc.
This year's team will not have anyone drafted next spring or even worth tracking. Will they have some in 2-4 years? Probably. I'd look back to the Urban's arrival for a similar comparison. The "clown show" actually had some talent, but it was not realized yet, and it wasn't close to what he'd build up in 2015.
