It's fun to jump on the bandwagon. Sparks fly as the hype train leaves the station, hopefully heading to a gold rush. If this was a movie, everyone would reach the end game happy. But sometimes, the hype train is a one-way ticket to disappointment along with the rest of the public. You don't want to be left holding a losing bet slip, muttering "would've, could've, should've".
In the sports betting world, there's a delicate balance between a smart bet that the public is on, and a line that has taken on so much public steam that it's time to go look somewhere else for value.
