I've been a Keim backer for years but my support is wavering. This has zero to do with off filed issues and more to do with how the Cards are being run.
Draftwise: I'm not as hard on him as others. The only 2 huge mistakes I think he's made were Reddick and Niklas. The draft is a crap shoot and his record is ok. The last draft shows promise.
Free agency: His approach to free agency is not working. The bargain basement, injury riddled guys does not get it done and hasn't gotten it done. They need to add bona fide talent, not hope somebody reverts to their form of one good year 3 years ago. I saw a quick blurb on ESPN yesterday that over the least 3 years, the teams that spent the most in free agency had their win total increase by about(I'm going from memory) 7 games the next year. The Bears, Rams, and Jax were the 3 teams I believe. So spending on players DOES work.
GM'ing: Keim is the GM and needs to act like it. I'm not a fan of the Kingsbury hiring but am willing to see how it works. That said, KK, along with subsequent hiring of Clement, was hired to coach this offense with Rosen, who was the #1 pick last year. If Keim doesn't think KK can do that, he should have never been hired. To acquiesce to KK wanting a different QB is crazy to me.
2019 draft: This goes with the last sentence above. Taking Kyler Murray at 1 is a bad idea. I know I've posted earlier that I would take Haskins at 1 but I also know, and agreed, that it was very unlikely and not a very prudent move. The Cards knew they had the #1 pick when KK was hired, if they didn't have a plan, well that's another strike against Keim.
As for Murray, I have talked with someone, with no scratch in the game cardinals-wise, and( I'm paraphrasing), was told he has zero concept of an offensive scheme and is one of the least prepared QB's he's ever seen when it come to offensive structure, route trees, protections, coverages, etc. He's not remotely a Russell Wilson-type leader either. He excelled by being the best athlete on the field. That's likely not going to work in the NFL.
Is Keim really going to tie his, and the franchises future, to a 1st year coach and a playground QB and expect to be successful? I guess there is a chance for that but I think it's a longshot at best.
