Gotta love blurry-ass Scal in the background.

The Celtics have had discussions with free agent Jarvis Hayes about joining their roster. (CSNNE)

As much as the Boston Celtics need to add a perimeter defender coming off the bench, it wouldn’t hurt to add another backup shooter to the mix as well.

With most of the higher-priced shooters off the free agent board, CSNNE.com has learned that the Celtics have had some conversations about one of the best still available, Jarvis Hayes.

Go ahead and laugh at A. Sherrod Blakely calling Jarvis Hayes one of the best free agents still available. I know I got a good chuckle out of that. But the truth is, I’m kind of intrigued by a couple things Hayes IS (scorer, jump-shooter) and a couple things he ISN’T (Larry Hughes and Ime Udoka). That said, I really hope these wings we keep hearing about — Adam Morrison, Hughes, Udoka and Hayes — are the guys Ainge is looking at as 12th men. Because if any one of those four is playing significant minutes next season, the Celtics might as well forfeit the next 82 games. If there’s one thing I’ve learned about NBA basketball over the years, it’s this: You don’t win a ring with Jarvis Hayes as the primary backup small forward. You just don’t.
