When I heard the name Greg Gaines, I had to do a double-check on the age and relationship status with another Greg Gaines.   Do not know how far back that you go, but in the 80's there was a linebacker that played for another Seattle team that was also named Greg Gaines.   No relation as far as I know.   
I think Dawgs will be alright at receiver.   We do get some good QBs in the state.  At one point we even had a family of them.  Remember the last name?
