Chiefs' Alex Smith says there is more turnover in the NFL than people realize, including the 49ers

Kansas City Chiefs QB Alex Smith is in Tahoe for the American Century golf tournament and so is a 49ers reporter for the Mercury News, who caught up with Smith to ask about the crazy offseason the 49ers have had from retirements (Patrick Willis, Chris Borland, Anthony Davis, Justin Smith) to free agency losses (Frank Gore, Michael Crabtree, Mike Iupati, Perrish Cox, Chris Culliver, Dan Skuta).

"You knew some of that wasn't going to last forever," Smith said, via the Mercury News. "We weren't going to be able to hold it altogether from a cap standpoint and the years standpoint. You knew that was going to change."

Unless you're the New England Patriots, it's probably going to change. We don't know yet how San Francisco will react to all that change but if you go by the current Vegas odds, Alex is in a better situation in KC.

Alex also said in the article that people don't realize how much turnover there is in the NFL. "It's a lot more than people realize, I think," he said. To demonstrate this, I went back and looked at the offensive lines Smith has played behind, starting with KC's offensive line the year before he arrived and projecting what this year's line will look like. The number in parentheses is the number of changes on the line from one year to the next.
