Last year, Kearse and Stephen Williams were the 4th and 5th WRs. More often than not they were deep field specialist asking to stretch the field vertically.
Williams ended up get cut for Bruce Irvin. And Kearse took on a more all around role has Rice received less plays because of his knee.
So, I can see why the Seahawks drafted Paul Richardson, and were even looking at him at 32. He has a tremendous skillset that was obviously a weakness on the rest of the roster. Dude, has speed. He's fast, athletic, can jump, can make difficult catches, but most importantly, Richardson can track a deep ball.
I don't expect the team is worrying if Richardson starts or not, they more or less sat Tate for 2 years, but I also think they'll force his skillset early and often in the early going of the season to make Defensive Coordinnatoors respect his deep field ability.
And if Paul Richardson shows up in his opportunities and starts making the hugh splash plays that he's capable of, just think what Kearse, Miller, Baldwin, Lynch, Willson, McCoy, Norwood, etc, and Russell Wilson can do when Richardson and Harvin are both spreading out the field horizontally and vertically and taking multiple defenders with them.
Like Kearly said Richardson has the potential to be 25-30 catch guy with 400+ yards and some long TDs scores. If that guy shows up on the field, it would not surprise at all if the Seahawks would be enjoying a hell of an offensive season. Top 5 status. They were 8th or 9th last year per DVOA despite all their struggles with injuries and inexperience.
