While compiling data and researching for my recent piece on MyFantasyLeague.com's average draft position data.

- Jamaal Charles is a monster, but he's not as reliable as McCoy and Foster. Charles is fifth in usable weeks, despite missing nearly the entire 2011 season. He's got a usable week rate of 70.3%, which, again, is over 10 percentage points lower than what McCoy and Foster have compiled.

- Alfred Morris has been really consistent through his first three seasons, and will probably have a fair price tag again during August fantasy drafts. During his breakout rookie season, Morris finished with 10 usable weeks, and he's had 9 and 8 over the last two seasons, respectively.

- Le'Veon Bell already has 26 usable weeks through two seasons, despite missing time to start his rookie year. In 2014, Bell's 15 top-24 performances were the most we've seen by a single running back over the last five years.
