Back in June, ESPN Insider Matt Williamson provided his positional and Top 100 overall rankings of the best players for dynasty leagues for ESPN.com's fantasy football draft kit. His updated rankings, as of August 19, appear below. Note: The player write-ups remain the same except in cases where news or other developments have changed his opinion on a player.

Top 100

1. Calvin Johnson, Detroit Lions

Johnson remains the king. But for how much longer? The health of his knees is concerning. But Johnson is in an excellent situation. The additions of Golden Tate and Eric Ebron should shift some attention away from Megatron's side of the field. Johnson is still in the prime of a career that will soon be compared to that of the all-time greats. Even when he does lose a step, most cornerbacks still won't be able to keep up.

2. Dez Bryant, Dallas Cowboys

Bryant represents everything you want in a dynasty wideout. Although his name appears on the injury list more often than any owner would like, he is the featured player in a pass-heavy offense with a quality quarterback and a defense that looks to allow a ton of points this year -- and perhaps for years down the road. Despite the many questions about his health, there are few about his toughness: Bryant plays through his injuries and hasn't missed time since 2011. Maybe no coordinator in the league likes to throw the ball more than new Dallas offensive coordinator Scott Linehan, who helped generate a ton of production from Johnson in Detroit. Bryant is a touchdown machine and great after the catch. And he's only getting better.

3. A.J. Green, Cincinnati Bengals

Green is an elite talent with a long frame, uncanny ball skills and big-play ability. Although he had some down games last year and has a very average quarterback, Green has posted remarkably impressive stat lines each of the past two seasons. There is talk that the Bengals will throw less frequently going forward, but I would be shocked if Marvin Lewis allows Green's targets to decrease. The argument could be made that Green should top this list.
