Assistant coach Aaron McKie spent about 20 minutes feeding Jrue Holiday the ball for stop-and-pop jump shots at 76ers practice on Monday.

Coach Doug Collins was working out on an elliptical machine nearby. He said he did not notice.

"I didn't pay it any attention," Collins said. "I was sort of in my own world on my elliptical, just thinking thoughts about how I can continue to try to get the best out of this team. We're in a little bit of a tough situation. He'll let me know how he's feeling."

Holiday has missed the last two games with a sprained left foot. The Sixers' leading scoring at 18.4 points a game, he has been listed as day-to-day since he hurt his foot Wednesday against Chicago.

He worked up a serious sweat in his session with McKie, then pronounced himself pain-free. Holiday said he would try to push it harder in the team's shootaround Tuesday morning in Dallas. He hopes to be available to play Tuesday night against the Mavericks.

"It feels OK," Holiday said. "But this is a situation where it's my foot and it's probably one of the most important parts of your body. Not saying anything else isn't, but you can't do much if you can barely walk on your foot."

Holiday will be listed as a game-time decision. The Sixers will play 11 of their next 12 games on the road.

Defending the three. In a 111-98 loss to the Lakers on Sunday, the Sixers gave up 10 three-pointers in the first half and a season-high 14 for the game. Two days before that in a 95-85 loss at Indianapolis, Indiana made 8 of 14 three-point shots.

A huge part of this problem has been bad communication, Collins said. The coach said that as he and Holiday sat side-by-side at the team's shootaround Sunday morning, Holiday pointed out that he, too, noticed that the Sixers had not been talking at the defensive end.

"I said, 'Really? Really?' " said Collins. "I said, 'Tell 'em, Coach Holiday, because that's all they hear from me.' "

The Sixers have lost six in a row at Dallas. They have had trouble generating their own offense, especially in reaching the free-throw line. In their last five games, the Sixers have attempted just 77 free throws. In that same span, their opponents have attempted 122.
