Near the end of close games, the Boston Celtics have been a predictable bunch for years.

Get the ball in the hands of Paul Pierce, and let him do his thing.

At times it worked.

Other times, not so much.

But having a player charged with making the right end-of-game play, is a luxury the Celtics no longer have.

This was among the many challenges to surface in Boston's 105-98 loss to the Milwaukee Bucks on Friday night.

"That's part of who we are," said Celtics head coach Brad Stevens. "That's OK. I don't think that we would be able to say, 'this person will be the go-to guy every single night.'"

With Rajon Rondo still out indefinitely while recovering from a torn right ACL injury, the logical player to carry the Celtics in the latter stages of games would be Jeff Green.

While Green certainly has shown the ability to carry Boston at times, he puts the onus on who gets the ball down the stretch on Stevens.

"If he (Stevens) tells me to get the ball, I will get it," said Green who had 13 points against the Bucks but missed all five of his fourth-quarter shots.

In Boston's 105-98 loss to Milwaukee, they too are a team in search of a go-to kind of player.

On Friday night, that was Zaza Pachulia who had a game-high 20 points who scored six of Milwaukee's last eight points.

Gerald Wallace doesn't believe the Celtics need to have a go-to player.
