If there’s one thing the Celtics  never have to worry about it’s the availability of Walter Ray Allen . It’s almost taken as an article of faith that when the ball goes up, Allen will be there. For the first five years of his career Allen never missed a game, and since coming to the Celtics the 33-year-old Allen has been logging 36 minutes consistently every night, which is remarkable when one considers that the primary objection to the Allen trade was his health.
Allen played in the 900th game of his career the other night against Houston and it’s a testament to his career that such an accomplishment happened with very little fanfare. (Kobe Bryant  is the only other player from the 1996 draft class to appear in 900 games to date, and Allen ranks 10th on the list of active players for games played).
Allen’s career is a study in consistency, which is easily explained by his tremendous conditioning and his legendary pre-game shooting routine. There is no wasted motion with Ray. He is the smoothest robotic player in the game, and that’s meant as a compliment of the highest order.
A lot has been made about Allen’s revitalized play this year. He’s shooting 48 percent from the field (up from 44 percent last year) and just seems to be more integrated offensively with the Celtics system. There is an interesting quirk in Allen’s numbers , however.
While it’s true that his FG shooting is up, his 3-point shooting has actually gone down (from 39 to 36 percent), which brings up something Kevin Pelton from Basketball Prospectus  mentioned to me about a month ago . That is that Allen’s shooting on 2-point shots has gone up dramatically (from .486 in 2007-08 to .579 this season). Pelton feels that sort of trend is usually not sustainable, so it’s something to keep an eye on as 2009 develops.
Still, by any measure Allen is enjoying a very successful year. He has the highest adjusted +/- rating on the team, according to 82games.com  (which in layman’s terms means the Celtics are more effective with him on the court than off it than any other player) and the highest Offensive Rating, as well. Allen also remains the best starter option when Doc Rivers  subs in the second unit, which is both a blessing and a curse, since Doc would love to manage Allen’s minutes in the second half of the season.
