I shouldn't have to point this out, but open FA is not an excuse to add a shit ton of guys and then hold them through the preseason. If you want to give guys a tryout, that's fine, but you shouldn't be carrying like 10 WRs or something.
It's about finding a few guys to improve your team, not hoarding players. You're going to have to cut down to 53 for the preseason anyway, so please only sign guys you need for depth or who you realistically might use. Open FA is definitely easier, but if people abuse it we might need to close it off again. I certainly don't want to do that.
