All you have to do is watch him about 3 1/2 hours before tip-off.
Whether it’s a January game at the Garden against New Jersey or a potential championship-clinching Game 6 of the 2010 NBA finals, Allen shows up before everyone and has the floor to himself and start draining shot after shot from beyond the 3-point arc.
Tuesday here in Los Angeles was no different as he went through several series of solo H-O-R-S-E games on the floor before finishing with free throws. He is known for his work ethic before each game, getting on the court and warming up. It paid off in Game 2 as he hit his first seven 3-point attempts on his way to setting NBA Finals records for most 3s in a half  and a game  as the Celtics  won, 103-94 to even the series.
This is hardly news but still, it’s a reminder of the small details Allen keeps attention to, and that’s no easy task considering his diabetic four-year old son Walker just recovered from another bout of hypoglycemia early Saturday morning.
