Look at the comments on Kevin's insta post. Seems like the highschool boys think what Brendan did was funny and Kevin is just making a big deal out of it. Here are a few examples:
"Bro no one gives a f*ck about cross country ur lucky he even got your sh*t buzzin"
"He a legend…"
"Bro chill, it was pretty funny. Nothing interesting ever happens in cross country and for this happen was just something out of the ordinary 💀🤣"
"you acting like he murdered someone jeez pipe down"
"Y’all in the comments saying Kevin rolled Brendan but don’t know that brendan let him win on purpose cause why would he go and win a hs meet he was literally there pacing Kevin is what I heard"
And there are more. It's pretty clear that what Brendan did was inappropriate and inexcusable, but it seems like some of the highschool boys lack the perspective to understand that.
