Issues are reportedly already brewing behind the scenes between San Francisco 49ers head coach Chip Kelly and general manager Trent Baalke just three months into the new coach's tenure.

NFL Network's Brian Baldinger commented on the situation during an appearance Thursday on 97.5 The Fanatic: "I already hear there's problems in the building between Chip and Baalke."

Although there were no further details about the possible rift, it's an interesting comment considering how Kelly wore out his welcome in Philadelphia after less than three seasons.

That said, any issues between Kelly and Baalke would go against the public comments the 49ers' coach has made since taking over the position. At his debut press conference, he said, "I just want to coach football," and confirmed the GM would have control of the roster, per Josh Alper of Pro Football Talk.

"Trent has control of the 53, and I'm real comfortable with that," Kelly said. "I wouldn't be here if I wasn't. I think the way this personnel department is set up and how they structure things, I'm excited to be a part of it."

Kelly took control of the roster construction during his time in Philadelphia. That led to the exit of several fan favorites, including LeSean McCoy, Jeremy Maclin and Trent Cole, as he rebuilt the team to better fit his scheme.

Once the results began to fade—the Eagles were 6-9 through 15 games last season—the team let him go. The 49ers picked him up in January.

Taylor Price of the team's official website passed along comments from both Kelly and Baalke last month, and there didn't seem to be any issues. Kelly called Baalke's staff "very impressive," and the general manager felt their ideas for building the team were on the same wavelength.

"If you look at what (Kelly's) prototypes are, he's looking for the same thing we're looking for: big players, guys with size at their position," Baalke said. "That's part of what you're looking for when you hire a head coach—do you have a philosophy that marriages pretty well? It was evident early on."

Al Sacco of 49ers Web Zone commented on the situation and mentioned a possible solution:

Ultimately, either the issues have started to develop as the offseason has gone on or the problems are being overblown. But Kelly gained a reputation for having a "my way or the highway" approach in Philly, so it's difficult to discount Baldinger's report.

One thing's for sure: The 49ers have a lot of work to do rebuilding their roster after going 5-11 in the highly competitive NFC West last season. That challenge is going to become much more difficult if the decision-makers aren't on the same page.
