I run cross country and track in Suffolk County and I've raced against Mike Brannigan once or twice (Northport doesn't send their A Team to county invitationals besides the championships). He's an animal. I swear I have never seen a more perfected high school runner. It seems like he literally has no weakness. He's also a nice kid with a great coach, and the Northport kids are a bunch of bros too.
He's gonna be in the top 5 at NXN. No doubt.
I think the one possible weakness to Brannigan would be his team. Northport is losing everybody in their top 7 besides him to graduation, and the next best kid is gonna be a minute and a half back from him at their best. As a team they'll be weak next year but Mikey will still wreck in Suffolk and nationally.
