I don't think Tom Brady has been doing it all on limited talent. I think Edelman is a really good WR when healthy and they always rebuild with talent around Brady, that OL is surely one of the top of the league, and they have WRs who can contribute, are they the best in the league? No, not by a long shot but they have coaches who are great at what they do who put them in that position, I don't think the Ravens have that type of coaching staff.
They also have done a magnificent job of managing the cap and thats on the Ravens, bad contracts have hurt them, I can't argue against the deals given to Webb and Monroe but Pitta's is certainly questionable. Coming off a hip injury and you pay him 7M per year? That was one to shrug at admittedly. Not getting the return value on Webb and Monroe put them where they are I can't blame them to much for that.
In terms of Jefferson or Williams, I agree strongly with keeping both. The Ravens are not getting a #1 CB on the roster and why would they even try with Jimmy on the team, might as well go for the next best thing and that's getting a top level safety who will help shut down the deep passing game. In terms of Williams, I made my case about the DLs decline, having a guy like Williams who can take on two interior linemen and shut the run down early is super important. Someone here said it, forgot who but it was on the money, Ray Lewis advocated for Ngata because a guy like him who could take on two interior linemen gave the ILB a free runner at the ball carrier. Even if BW's pass rush isn't felt, the fact that he can take on two blockers proves pivotal to inside blitzes, and a big reason why Mosley/Orr did a great job at getting to the QB. Defense statistically was top 5, but I can recall Biscotti said they were just as responsible for the season ending the way it did.
I think the defense in the 1st round has plenty of good defensive talent but overall it hits a hard decline towards the middle and end rounds and the amount of CB talent decreases drastically. I'm fine with going defense if we go offense via draft. On the case of the starters, I think losing Wagner and Juice sucks but Wagner plays a position that isn't highly valued as the other positions on the line, same can be said for Juice who isn't even featured in some offenses. I think the loss of Steve Smith Sr. will be more felt than either. Personally, I think a good WR and TE would heavily offset the losses if we're expecting Stanley and Lewis to step up.
