Colin Kaepernick is still without an NFL team and San Francisco 49ers legend Joe Montana isn't convinced he'll sign before the season starts.

"I’m not sure, I think there’s an injury somewhere he probably gets in," Montana told Sporting News. "In most cases, you look at Tim Tebow — a great guy and everybody was talking about him. But what it comes down to is 40 percent completion or even in the low 50s, you can’t win in the league with that. You won’t be in the league very long. It comes down to his play as much as anything."

Kaepernick owns a 69-58 career record as a starter over his six-year NFL career, has completed 59.8 percent of his passes and has thrown 72 touchdowns to 30 interceptions.

"Everyone thinks it is the stance he took; one of the things you don’t look for is distractions in the locker room. You can go back to Bill Walsh and as soon as there were guys that weren’t fitting in what he was looking for, it didn’t matter how good you were. You weren’t on the team for very long. You have to have people who want the same thing, fighting for the same thing and willing to put in the time."

In addition to cutting ties with Kaepernick this offseason, the 49ers went through a complete overhaul and enter the 2017 season with new GM John Lynch and new head coach Kyle Shanahan in charge.

“I think changes were necessary there," Montana said. "I think it will take a year or so to get those guys understanding the system, how it works. I think there was a lot of loss for the game over the past few years with all the distractions, with Colin and all those things.

"They needed to clean house (and get) a different atmosphere in that building."

Whatever happens to Kaepernick, the 49ers are hoping their changes result in a change of culture after evening a franchise-worst 2-14 record last season.
