Four Games. Five Nights. Ten Exhausting Trips.

Welcome to the dreaded "4-in-5" -- the schedule quirk where teams travel around the country and across time zones to play four games in five nights. Yes, that's two back-to-backs in a row with just a travel day in between. With the NBA requiring teams to travel overnight for back-to-backs, chances are your favorite team is sleep-deprived. And thanks to an extended All-Star break this season, the NBA schedule will call for more of these sleepy bear traps, almost 70 in all. Here are the 10 longest 4-in-5 treks of the 2014-15 season. Buckle in. And sleep tight.
