I think some of this stuff about Whiteside and players not personally liking him is a reach
Breh, I've kinda noticed the same thing. I feel like Bosh is kinda annoyed because he's a low ego kinda dude who always leads by example and Whiteside seems more like he's worried about his stats.
Even when Bosh's shot isn't falling or he isn't involved in the offense, he gives 110%. It's one of the reasons he's one of my favorite players.
Its like Whiteside doesn't understand that the offense is more dangerous if Bosh cooks he has to be tightly guarded from everywhere on the floor which gives all other players more space to cook.
Whiteside's ungodly offensive rebounding ability means teams have to either commit to boxing him out or try to contest other teammates drives/alleys meaning he's actually a bigger threat when he's not given consecutive post ups.
Spo is actually using him pretty damn well and gives him a pretty big leash when he creates a presence inside (Will usually let him cook till he starts forcing too much) but Whiteside feels like it should it be a post up play all the time.
