Unless he changed after his time off. During his hot run, golfers who were paired with him routinely mentioned he would talk to his caddy and would totally ignore the other golfers.
Most guys have said he is very friendly - I've never heard that he wouldn't talk I guess.
He and Gary Woodland were talking the whole final round in the PGA. You are correct that he has changed and he is way more talkative now, but I think players liked him before too.
