Your overall point isn't badly taken, but you have really overstated on Ellis. First round talent? Ellis was a reach in the 3rd round and proved it by rarely being active during his rookie season. That is NOT what you get in a first round talent.
You are right that neither Wilkerson or Ellis are QB sackers, rather they are run stoppers and pocket pushers. Its in Coples that the Jet FO hopes will be the dynamic player of the 3. He was picked to become an impact player, a game changer, and the guy OC's have to game plan against. If he isn't any or all of these things then even if he turns out to be a competent starter, it will be like DRob revisited only without having to trade up and over pay.
