I "lucked into" the Dallas D 2 weeks ago in one league, and lo and behold I looked and they are sitting on the wire in another of my leagues.
Its a 10 teamer, but I have no one to drop. My bench looks like this Zack Moss, Devin Singletary, Austin Ekeler, Justin Herbert (BYE and I ain't cutting him lol) Brandin Cooks, Michael Carter Javonte Williams.
We start 3 WRs, and Cooks is my only extra WR, can't drop him either.
Might have to drop Michael Carter. (I'd prefer he puts up points on MY BENCH not someone else's team)
I know, first world problems right.......?
Point is, I absolutely believe like Tigerz said above, if Dallas is available, you should try and acquire if you have any way to get them. They are one of the few plug and play options at defense, and they might just have been dropped (or will be) because of the bye.
