NFL Network analyst and former NFL quarterback David Carr likely put himself on the bad side of San Francisco 49ers fans forever on Saturday morning when he said that Joe Montana is a not a top 10 quarterback of all-time:

Carr credits Bill Walsh's system in San Francisco for making Montana look so great, saying that defenses simply were not ready for what Walsh brought to the table. He also said that Steve Young, who followed in Montana's footsteps, was a “far better” quarterback than Montana.

His main point? Montana “arrived at precisely the right time.”

Given that Montana won four Super Bowl championships, three Super Bowl MVPs and a pair of regular-season MVPs, it's going to be tough for Carr to really convince anyone that Montana is not a top 10 signal-caller to ever play the game.

Keep in mind that Montana was posting great numbers when the passing game still was not even close to fully developed yet in the 1980s. Now, guys throwing for 40 touchdowns is seen regularly, and even Patrick Mahomes throwing for 50 does not come as much of a surprise.

But back then, when Montana was throwing 31 touchdown passes in a single season? That type of stuff was not too common, and the fact that he led the Niners to four Super Bowl titles in a span of nine years is pretty incredible and is something that not even Tom Brady, who has six rings, has done in such a short span of time.

Basically, Montana is one of the best quarterbacks ever, and arguing that he isn't just because of Walsh's system seems pretty silly.
