Might be able to get a very late 1st or 2nd. I'd look at Houston who will probably be without Tank Dell next year and Diggs is old always wears out his welcome. Buffalo is another option. Miami would be an option since Hill will probably force his way out and they are super finesse.
It would be better for the Saints and for him if he just put on the muscle, got stronger and just evolved his game. He's smooth and a tactician who just happens to be fast. He can sacrifice some speed for size/strength which would compliment his route running and hands.
