MISSOULA — Midway through the Montana football team's first spring practice on Monday, Eminem's 2002 hit "Without Me" played over the loudspeaker.

Eminem's repetitive "guess who's back" refrain had just a little more meaning inside the snowy Washington-Grizzly Stadium with Bobby Hauck at the helm. 

"It's great to be back on this particular football field," Hauck said ahead of practice. "It's always good to be out here with the team. Everybody's excited, we're ready to go and hopefully we can get a little work in."

Hauck said several players from his first team at Montana in 2003 have stopped by his office since his hiring in December to share some stories.

"It's fun talking about how these guys are responding versus how they did," Hauck said. 

Hauck isn't the only coach on the staff who's previously been with UM. Current wide receivers coach Brent Pease was the Grizzly offensive coordinator from 1996-98 and current offensive coordinator Timm Rosenbach served in that same role in 2012. 

Rosenbach said it was "a little weird" being back on the field but once the team gets to know each other a little better, "everything's going to click for us."

Rosenbach, who spoke after practice, said the team will be better on Wednesday. 

"It was ratty, but they were running around pretty good. A lot of guys have to learn what they're doing and stuff, but we don't really change anything from Day 1 to Day 2 though," he said of Monday's practice. "They'll pick it up a little better on the second day. The effort was decent but not where it needs to be yet."

Rosenbach added that the energy was high, but the nature of that energy was manufactured. 

"A lot of that's kind of false because we're having to generate that by running around and screaming and hollering and stuff," Rosenbach said of the energy at the first day of practice. "Hopefully they can start to do some of that stuff on their own as they go through this."

NOTES: Overly reading into Xs and Os and prospective depth charts on the first day of spring practice is futile, but there were some notable changes on day one — position changes. 

"We're going to let guys compete for spots on the roster and the depth will change every day this spring as guys have good practices or not and I think the competition will be fierce," Hauck said. 

Caleb Hill, last season's second-string quarterback, moved over to tight end. Hill's not the only tight end on this roster as Colin Bingham, Matt Rensvold, Trase Le Texier and Bryson Deming round out that position group. 

Heading into spring ball, the sheer numbers on the offensive line were abysmally low. Thayne Jackson's hip surgery didn't help those numbers either. (But Jackson was out and about with his crutch on the sideline and was in good spirits.) Esai Longoria, who was a defensive tackle last year, has moved over to offensive line. 

On National Signing Day, Hauck said that position switches, especially from wide receiver to defensive back, were inevitable. 

Kobey Eaton and Nick Fouch, formerly wide receivers, have moved into the secondary.

Other position changes are as follows: Jed Nagler, also a former wide out, is now suiting up at linebacker. Dante Olson, a former linebacker, is listed as a defensive lineman. Josh Deshner didn't have a designated position on the roster last season. He's now in Justin Green's running backs room.
