Yes, you would have collected his points if you had started him. Notice how you can't change your lineup now, but you will be able to after the Monday night game ends. You will want to change your lineup - possibly every week - based on who your players are matched up against (or if they have a bye week).
So for now, there's no way to have known New Antonio Brown would have done this well - I guess unless you were really paying attention - so I wouldn't worry about it. You might consider putting him in next week, especially if you have an under-performer in the WR department that needs to be replaced.
You can propose trades for any drafter player. If you want to pick up an undrafted player, click Add Players to bring up the free agent list. You just need to drop a player each time you pick up a new one.
I just checked and we were all smart enough to avoid Zurlein, so good job everybody.
Haha. And Tom Brady just did a commercial for FTX. Maybe he'll become a shitcoin whale after he retires, just for the lols.
