No matter what the Detroit Lions do at the tight end position this offseason — Eric Ebron is under contract with his fifth-year option, and Darren Fells is an unrestricted free agent — Michael Roberts is ready for a bigger role in 2018. Roberts played in 15 games with three starts last season, and was used primarily as a blocker. He caught just four passes on the season for 46 yards, and his immaturity got him suspended for violating team rules in Week 17. But the Lions’ fourth-round pick last year out of Toledo said he’s confident he’ll make a big step forward in his second NFL season. "I’m not hoping,” Roberts said at the Super Bowl earlier this month. “Honestly, I made a few mistakes. I did things a little different than I’d like in my rookie year and man it really just taught me so many different things. I learned a lot about myself, about the organization, about how to be a professional all the way around. So just excited." Roberts said he expects to play next season as an “every-down tight end,” the role the Lions envisioned for him coming out of school.
