I think Odell Beckham Jr could have a big year, but he's valued pretty low right now due to recent injuries. The Ravens are paying him a lot of money, so I'd expect them to use him. His knee seems to be fully healthy now. He was great on the Rams but admitted he played with a messed up ACL the entire time (until it fully blew up in the Super Bowl), so now that he got proper surgery and is in better shape, I wouldn't be surprised if he performed better than he did for the Rams.
Some deeper sleepers are guys like Richie James, Parris Campbell, Tutu Atwell, Michael Wilson, Trey Palmer, and Bryce Ford-Wheaton. All guys that you can get for cheap or really late who could potentially be flex-worthy this year.
Who are some of your sleeper picks for the upcoming NFL season?
My dynasty sleeper this year is Dewayne McBride. Way too talented to not have any impact, especially after Cook left.
As a Vikings fan I would love this. He seems to jump off the charts as a pure runner.
