#6 or #7 for Thompson is highway robbery.
Honestly, I think your opinion here is possibly being a bit clouded by your obvious love for the Dubs, and the fact Klay is one of your binkies. No disrespect meant though, we all have player's we're 'in love with'.
If I was GSW I'd want a slight bit more than that, but it certainly is not highway robbery. Klay isn't the role player Chambers suggests he is, not by a long shot, but he isn't some sure-fire perennial All-Star either.
