The flashbacks are back, like an uncle who tells the same story at every dinner. The episode tugs at the heartstrings with the subtlety of a bell-ringer, and somehow it still works.

Long-time viewers get a payoff: "how do the players in the locker room feel to be on the b..." is no longer a mystery. Not a classic, but a very good Tuesday.
