Thanks Jville!!! Adding 17 players to the roster but then removing them when the names are wrong is extra work I'd prefer to avoid.
Jville thanks my friend, I suspect you are right, on the draft picks being unsigned thus allowing for more UDFA players to be "considered signed", but only for a look see until they are waived or released.
I'm going to wait until the team announces those UDFAs they plan on signing and keeping although I'd probably add the names when the team says these are the signings they will make. I might treat then all as tentative signings on the OP.
