Lightning gets easily confused (confused making fun of him with stalking him). So I could totally see how Lightning gets this impression, it probably goes like this:
Lightning: Walks up to a group of 5 coaches and says, "Hey guys, can you believe that Fran is going to play CW and Bohannon at PG. I mean what is what with that, what an idiot, those guys suck, and we are going to finish in 9th or 10th place in the B1G, "unless they get lucky" with those scurbs."
Real Coaches: "Um, ahhh, yeah sure"......walk away to get away from Lightning.
This is exactly what I was thinking too. If Lightning isn't messing with everyone, it means he's a huge tool and the exact type of person who would illicit responses like you said in your post. In real life, I nod my head and say "yea" when people are saying stupid shit all the time.
