I by in large agree with you. I'm not the biggest Lee Evans supporter. But I re watched probably 30-40 games during Evans' tenure and watched all the games from last year to try and convince myself that Lee was commanding the attention all his apologists say he did. It's a difficult thing to do because obviously the NFL filming follows the ball and rarely gives a glimpse of the entire field so you can see where everyone is lined up. But when I could see, by in large Evans was commanding safety help (double team).
They weren't worried about him slanting hence there would have been more LB involvement. It was the over the top safety help he commanded (go route).
In saying that, this team needs someone to emerge or I believe Stevie Johnson will struggle this year. Stevie by himself isn't a #1 receiver, he needs the scheme to help him. He isn't big, he isn't fast, and I'm not 100% sold on his hands. He put his name out there nationally doing the interviews etc. I have no issue with that, but he's being noticed now by defenses. I feel he's most likely going to get a LB shading his way and/a safety. If these other guys don't burn teams for doing this it's going to be tough to move the ball in chunks.
