AIR FORCE ACADEMY – Chad Hall stood five yards away catching football after football shot towards him by the jugs machine after Wednesday morning’s Air Force practice.

He was doing the same thing before and at the conclusion on the afternoon practice session because it’s become a pre- and post-practice routine this season.

New Falcons coach Troy Calhoun is demanding that everybody that wears an Air Force football uniform develop into complete players.

That’s especially true for Hall, the 5-foot-7, 180-pound senior who was the Falcons leading rusher last season as a halfback.

In Air Force’s new multiple offense, Hall is now a wide receiver-Z, a position that requires him to catch the ball, run the ball and block.

"I’m comfortable with it (new position)," Hall said. "They say I’ll carry it and touch it just as much. I’ll do both. I can’t wait. Hopefully I’ll get some mismatches against linebackers.

"We can do anything out of our offense. We can do the old stuff, we got all this new stuff and we’re going to surprise some people."

One of the first moves that Calhoun made last spring was to switch Hall to the Z receiver position and let other players battle for the starting tailback job.

"He’s a versatile guy," Calhoun said of Hall. "We want a guy there that can run with the ball well. He has good quickness. He’s elusive in the open field and he’s a guy with good ball skills.

"And I can see him adding another responsibility and that is punt returner. He did it a little bit as a sophomore. If you’re a punt returner, you have to have guts and confidence. He absolutely has that.’’

Hall gained 784 yards last season, the most by an Air Force halfback in 18 seasons but now he’s watching to see who will be the Falcons tailback this season.

It’s something that Calhoun doesn’t know and he hasn’t ruled out incoming freshmen from challenging in the position battle.

Calhoun, who has chucked the triple option formation, wants to find a hard-nosed tailback that will carry 20 times a game.

Senior Kip McCarthy, who gained 144 yards in 21 games over the past two seasons, has moved from third to first on the depth chart after strong performances in the past few practices.

Calhoun expects he may have as many as five freshmen in the two-deep lineup and one could possibility be tailback Xavier Stephens.

HUNGRY KICKER: Junior place kicker/punter Ryan Harrison, who was limited to kicking in practice last year because he was on probation for a violation of Academy standards, had a good day in the morning kicking field goals, including a wind-aided 55-yarder.

"It was a little frustrating last year but I think I learned a lot about myself and what I can go through and kind of used it to build on," Harrison said.

"I had a year to kick in practice and work on some things. I didn’t get to stay for the games. It makes me that much more hungry. The whole thing, being off the field, kind of taught me things that maybe being on the actual field itself I would not of had a chance to learn. I kind of have a cool perspective on everything. I appreciate it that much more and I’m that much more hungry to get back out on the field and play."

INJURY REPORT: Tailback Jim Ollis, a converted quarterback, will be out for two weeks with a injured ankle and offensive tackle Dan Holder could be out four to five weeks with a sprained knee.
