I think you overrate their player personnel skills. They are not very good in FA, for example, especially recently (say last 4-5 years). And their drafts have been good at times, poor at others.
They aren't the worst front office in football but, at best, they are middle of the pack and that's largely because of Jerry and Stephen.
I agree with you on Garrett but then, for example, look at that Eagles team that just won the SB. For all the talk about how good Jerry and the front office are about getting talent, that Eagles team is a more talented group. So frankly, Jerry hasn't built a SB caliber roster that's just being let down by a poor head coach. This franchise has talent and coaching issues........... and that's all on the front office.
You're going to miss more often than not, usually, when you are signing lower tiered FAs. The guys they signed were to be stop gap players.
Thornton was a bust. Paea just quite on the team.
Carroll had the one bad game and was basically cut because we had young talent we got through the draft. But he was signed before the draft. You have to consider that as well when these FAs are signed. You don't know what you will get in the draft. And if you draft well, you can replace some of the guys you picked up as stop gap.
Irving is solid. We just resigned Price, who has potential. Mayowa wasn't awful. He had a few good games. Even a couple of the DTs that played last year showed a little something.
Alfred Morris, Jaylons brother, Carr, Cooper played ok.
I'd say the are above "middle of the pack". You have to consider the draft as well. The draft being by far the most important piece. And they have been very successful there over the last 5 years.
