I would say the biggest improvement has been the pass rush.DBs tend to be much closer in their coverage 3-4 seconds into a play as opposed to 6+ seconds into a play. Front seven has been getting it done in general.
When you factor in the price tag...I have no problem having Joseph over Nnamdi. At all. Thus far, JoJo has had a much better season and has made many more plays.
Well it allowed us to get Manning. If you're telling me Manning + Joseph > Nnamdi that's fine. But Nnamdi is the best CB in the league, its not my fault the Eagles put him in zone. Also, in a typical season I'd expect Joseph to make more plays, Nnamdi discourages the pass from ever being thrown.
Not sure how you can say Nnamdi is better that Revis right now. The guy has found a way to somehow step up his game this year even higher. And Joesph is, with out question, having a better season than Nnamdi... Though I'm not saying that Joesph is necessarily a better DB.
well you said Nnamdi is the best choice even factoring the price...I was factoring in price. And JoJo is a more well rounded corner though, i.e. he's a very good tackle and plays well in both zone and man.
They feed off each other - last year, there were plenty of times when there was an effective blitz that came up empty because the QB had a wide open target in 2 seconds. 1 competent DB out of 4 was tragic. Now, the DB's can hold their own. Okoye's replaced with Watt, giving the line serious disruption down after down. Smith and Cushing were both better than it appeared last year, they just couldn't get the results to prove it. Now they can. The DBs get relief from QB hurries, the front 5 get an extra second or two from decent coverage. Tons of credit all around. The front office made fantastic moves regarding the defense.
Nnamdi has had a good season, but not on the level of Joseph so far. This season alone, Joseph > Nnamdi, both in play and in price.
While it's possible Nnamdi has been riding his reputation for a season or two, it's really hindered him trying to learn some complicated cover scheme taught by a OL coach turned DC.
