What It Means:

Charles' only other free-agent visit this offseason was with the Seattle Seahawks. He's been limited to eight games (five starts) over the past two seasons, but the 30-year-old back would provide an impressive complement to C.J. Anderson if he can stay healthy.

Charles has attempted just 83 rushing attempts over the last two years, but that's come with 0.08 Rushing Net Expected Points (NEP) per carry over that span of time. That would have been top-10 in the NFL in 2016 among the 54 backs with 80 or more carries. The Broncos, meanwhile, finished fourth-worst in the league last year in terms of Adjusted Offensive Rushing NEP per play.
