I dunno how one would rank AZ's defense after 5 games in 2021, but at this point I wouldn't place them in the top ten. I think the 49ers even with injury has a better defense. That's what kept them in the game against AZ, at home.
What could be extrapolated from this game: is Lance on 3rd and long as opposed to 4th and short. That''s on Kyle Shanahan. The hot seat glowed a bit today for Shanahan, he is underwater in the W/L column and there is no real horizon this season for the 49ers. If Lance turns out Vikings Teddy Bridgewater or Jets Geno Smith, given what the 49ers gave up to draft Lance, well let me put it this way: the 49ers have just entered the full rebuild mode two seasons removed from the Super Bowl.
Given how much they are bleeding in cash due to Levi's Stadium, and only a few million from being capped out, along with a penchant for acquiring injury prone talent, Lance's value can only be measured in game day fantasy points.
