Age matters for Fantasy football, but it's only a minor consideration when you're just thinking about 2020. Oh sure, all other things being equal, you'd take a 26-year-old over a 31-year-old, but you're not taking Calvin Ridley over Julio Jones just because the latter is older.

But you might make that move in a Dynasty league. Jones helps your chances of winning in 2020 more, but Ridley may have five years of high-level production ahead of him, whereas you can't guarantee anything beyond 2020 for Jones. It's a tough choice, but being ahead of the curve is everything in Dynasty.

Heath Cummings is here to help you stay ahead of that curve, with his latest updated Dynasty rankings. First, we've got an all new top-150 ranking and trade values chart, just in case you're looking to re-tool your roster before training camp. Then, Heath gives his updated running back and wide receiver rankings, with a specific focus on a handful of players who could shoot up the rankings with a good preseason. It could be worth making a move to stay ahead of the competition.

The Dynasty trade chart shows you should be very careful with players approaching age cliffs.

Whose value will rise in the next two months, and who will be potential buy-low candidates?

The sky is the limit for Calvin Ridley and D.J. Chark as they move into what could be the best seasons of their careers.
