I agree that this is the year Jefferson could put it all together plus I believe he will be somewhere else next year too. As to Atwell, I liked what I watched with Mayfield at QB. Atwell proved he could run routes and make catches as he is more then a one trick pony. Yes, you will have to limit him somewhat because of size, but overall, I believe he can be productive moving forward.
I understand why everyone is not a fan of Atwell, but let the kid play and again last year, he made some good plays more then just running the fly pattern.
