You say that but mysticsniper seemingly didn't, believing that Leicester could keep their players and judging by his 2nd post that players would want to stay. I was genuinely interested by his and others responses because it seems like a lot of people making these statements don't realise what they're saying.
The first thing that will happen is legal action, BT/sky would say contract void then EPL would sue the 6 clubs for lost earnings.
After that I expect contracts with players would be renegotiated, players that dont accept it would be put on transfer market, I expect some would at least see out rest of contract on lower salary, so I think some players would be kept, but some would be lost.
The league would have much less high profile players, but ultimately what counts is the sport, the competitiveness of the league, the championship e.g. is one of the best leagues to follow/watch as its so competitive. Also to me keeping cup competitions intact is important as well.
As to what the players want we dont know, as has been pointed out to you, these decisions by the the clubs that made this agreement have likely been by the club owners, not the managers or the players.
