I won't argue that there weren't similarly-priced guys out there across the league who ended up being better values or who would have been better signings than the guys we kept/brought in. Obviously, we whiffed on some of those guys, and that hurts us. But a certain amount of whiffing on players comes with the dinner, right? And the whole idea on buying low is to keep from betting big on a guy you don't know will fit or where you don't know what sort of person or effort you're really going to get.
But, if you're going to build through the draft, you can't miss on guys like Gregory and Jaylon and Awuzie, and Taco. You're saying "I'll go light at FA, because I'm going to make it up in the draft," only you don't make it up in the draft, you crap the bed, instead. If that was your plan, and you didn't fill the holes you thought you could fill using your valuable draft resources, then that's where you place the blame. It's not that we need better stop-gaps. It's that we can't keep whiffing on core defensive starters we draft to develop and expect to get any better.
