Good, he has every right to feel disrespected - he's a solid starter having a career year on a good team, is very underpaid, and the home fans are cheering for an opponent at his position that they want to sign. Blowing up on social media isn't a good look but I'd be more worried if he didn't take it a little bit personally.
I also think Crowder is the kind of guy to take feeling disrespected the right way - use it as motivation to bust his butt to get better like he has his entire career so far. I don't see him becoming a bad locker room influence all of a sudden because another guy was getting cheers one night in January. The Twitter blowup is embarrassing and hopefully an aberration but I actually see the overall situation pretty positively for Jae. Just keep it off the 'webs buddy!
