His "apology" was perfect.
"I think everybody’s seen on social media everything that took place this week,” Kelce said at the top of the Monday night show. “I’m not happy with anything that took place. I’m not proud of it. In a heated moment, I chose to greet hate with hate, and I just don’t think that’s a productive thing.”
The only people he should apologize to are
1. his bosses, who I am sure are quite satisfied with that apology, especially with no backlash, it seems.
2. The vile little toad whose phone he smashed.
I don't care if he apologizes to the toad, so I don't really see anyone else who should be looking for an apology.
