I do realize that, and those player counts are NOT irrelevant. they need 90 for camp. So those players on contract will go down as they clear space if cuts are needed, meaning for the UFA purposes more players will b hitting the market within 24 hours.
Figure teams have 7 draft choices and sign roughly 13 UDFAs. So going into draft you would want roughly 65-70 on contract to get to your 90
