I would beg to differ here (seems to be a theme today ).
Monitoring the FA situation obviously is relevant only for dynasty formats. But there, it is highly relevant. So relevant that, 2 years ago, I worked it into my magic Excel spreadsheet that spreads all that fairy dust across my fantasy leagues.
For players you currently hold, it’s extremely important to know about their contract situation. Players like Schultz and even Jacobs or Saquon are good sell candidates before the trade deadline (or “would have been”, for those leagues where the deadline passed already), if you can afford to lose them for the ROS.
They are at peak value now, but may lose value after the season, depending on how their contract situation will play out.
Even if they stay with their teams, it’s not likely they will gain any value. So now is the time to cash in on them, unless your team is a contender for the title.
And then there are players you don’t hold right now, that you can consider stashing on your dynasty teams before the waiver wire closes.
Those can be players who could replace your current starters next year. No luck here for Saquon owners, as the Giants will most certainly not use Matt Breida as their RB1 next year.
For Jacobs owners, they could consider stashing Zamir White, even though I would hold any bet that the Raiders either re-sign Jacobs, or draft another RB next year. But you can still drop White in that case. It’s not like it will cost anything to add him right now.
For Schultz owners (I am one myself), I would definitely recommend to stash rookie Jake Ferguson. He already flashed in Schultz’ absence, and if Schultz and the Cowboys will part ways, he could inherit the role. If he will become as valuable remains to be seen, but he’s as fine an offseason stash as they come in dynasty.
And of course, you can also stash these players if you don’t own their current starter. Jake Ferguson might be able to help your team next year, regardless of whether you own Dalton Schultz right now or not.
What indeed rarely works out is stashing players that will become free agents after the season, hoping that their situation will improve with a new team. I usually take that gamble only for QBs who might have a chance to earn a starter role somewhere next year.
Last year, Geno Smith, Mariota and Trubisky made good offseason stashes. Of course, there is no guarantee. Those who gambled on Drew Lock or Tyler Huntley have not been rewarded. But the Geno owners who added him while he was still available for free certainly are happy campers right now.
TL;DR: yes, the FA market is unpredictable. But so are injuries, coaching changes or sudden TD surges. We have to take our chances, and especially in dynasty, playing the FA market right should be a vital component of that.
