Had this come to me in a literal fever dream last night - there should be a league option to have a halftime substitution if you’ve got two players in the same game. If you started a WR in your flex who does absolutely nothing or got injured in the first half, and a RB who is clearly on a roll, at halftime, you can swap them - losing any points the subbed out player already got and only gaining new second half points scored by the player you subbed in.
It would lead to even more investment in following the games on the day of, add a wrinkle of maybe wanting to grab multiple guys from the same team, and let you throw some Hail Marries with either boom or bust guys you could sub out after the first half if they’re busting, or bet it all on a swap to sacrifice whatever points you’ve got for the prospect of so much more.
And no I’m not just salty that I couldn’t do this for Davante and Josh Jacobs on MNF 😆
