Exactly. The run defense is one of the worst in the league (30th or 31st?) and Simmons is an average run defender at best; PFF ranks him like 75th out of 160 DT's against the run. There's no rhyme or reason to how Poles and Warren are constructing this roster. They acquired some upgrades, sort of, on the Off Line in the offseason and the OL is still ranked around 20-22nd in the league both pass blocking and run blocking.
And they've got Swift as their main back, the same guy that Ben Johnson let walk from Detroit.
I just don't see it with Williams. Sure there's talent there, but I just don't see it between the ears and I don't see it in regards to character. We'll see, but Goff worked so well in Johnson's scheme because Goff could stand in the pocket and throw the ball. Williams seems incapable of doing that, most of his plays come from escaping the pocket. Johnson is probably pulling his hair out trying to coach that out of him.
I'm biased against the Bears of course; not just being in the Vikings division but I also have strong betting positions on the Bears in the Bears not making the playoffs, Bears winning less than 9.5 games, and the Bears winning less than 6.5 games (that's a longer shot, I may not hit on that one).
