Allow manager to put in waiver claim on a player, even though they were the one who dropped them.
Sometimes when I drop someone and then during the days he's on waivers, something changes and I may be interested in having the player again. But for some reason, when you drop someone, you're not allowed to make a waiver claim for them, using the standard waiver system. You can make waiver claims in the FAAB system on your own dropped players. So why not in standard waivers, too?
Because if you have the #1 waiver claim, you are effectively expanding your roster by 1 position.
You have 2 top QBs and they both are on a bye week and you have the #1 priority. You could drop either QB, pick a sub for the week knowing you could retain the player thru a waiver claim and have them back on your team.
FAAB is different because it is bid based, not waiver priority based, so you can buy back your player if you are the high bidder. If you are not the high bidder, you don't get the player back.
