Jackson spent much of last season injured, but gave us a clear picture of who he is in today's age. His performance in eight starts would translate to 1050 yards and 8 touchdowns, which would have put him in the same company as Maclin and Sammy Wakins. If he can stay healthy, you've got yourself a very fine value this late.
I've never been that high on Jackson, but his big-play ability keeps him in the fantasy points and Kirk Cousins proved he was a capable quarterback last year. I doubt I'll target Jackson since I love receivers who actually get targets, but the results are usually ahead of where I have him ranked.
