Fantasy football: Stock watch and rest-of-season rankings

Clay: Plenty of upside for Ronald Jones (1:29)

Field Yates and Mike Clay break down the impact Ronald Jones can have this season in fantasy. (1:29)

One week down, 16 more to go. Welcome to the first 2019 in-season edition of the end-of-season rankings! Each week up until the fantasy playoffs we shall rank the players -- and defenses -- for the remainder of the season, by position and overall, in an effort to monitor relevant changes and aid in trade talks, barroom conversation, whatever you like. This season, we are merging an oldie and a goodie -- the Stock Watch -- into this file, so look for players on the move within each position with brief discussion points as well.

Each team has played only one game that counts in the standings, so let us just say that the preseason rankings have not exactly been overhauled. That is not my style. If you liked Baker Mayfield, Aaron Jones and Stefon Diggs a week ago, um, did something really change? They simply did not have impressive Week 1 games. Be patient. If we are still talking about them -- and myriad others -- as disappointments in a few weeks, then sure, it will really reflect here in their rankings. I am more patient than that.

That noted, there are some changes, either due to injury or opportunity or just because I do feel differently about a player than I did a week or two ago. No, Lamar Jackson is not a top-five quarterback. Not yet.

As always, enjoy and good luck this season!
