Why PHI do it:
Hayward is a player that can give quality 25 minutes in playoff games
He's still an expiring that let them do what they want in FA
Hayward doesn't require spending a first round pick
Why CHA do it:
Send a veteran to a contender to give him a chance to play playoff basketball
Sell a player for some seconds instead of buying him out
Add far into the future seconds to their arsenal of picks
