Nfl rules would allow one player to be optioned a 1/2 season IR that allows the player to return mid season. I'd like that avialable here.
As for PS's, to me they are for farming young players. Seeing who has potenial to use on your team or trade for a better future pick. The Nfl allows players who played less than nine games in two seasons to practice on that squad. Its a small percentage of poolable players that fit the NFL criteria worth holding on to besides future value. I would enjoy some version of a PS.
To me I have a hard time cutting guys, being only able to trade thier value in the preseason. When a few weeks later when Injuries to other teams could increase value of young guy with potential. Futher promoting trades rather than saying they will available in FA anyway. I find a number of decent FA's that who are on the down swing. not with an upward trend. I would cut a better player now to ensure that upward trending player stays, but when its a few points holding on to a player only hurts his career.
A properly managed PS could get that guy playing somewhhere. It would make the game harder in terms of holding on to good young guys. Forcing teams to play the best players cause others will trade some talent to win now.
But really the benefit attained by most compared to the complication with explaining the NFL stlye PS's might turn players off as some can use it to thier advantage while newer owners might have a learning curve possibly furthing a gap of talent. But in a league of veteran owners who know the game a PS would be welcome. Well at least for me and Gus.
