In general:
From a media/fan perspective, there is too much weight given for player natural gifts and too little weight given for player development. Indeed, the ranting over talented players typically only comes post development. Tom Brady, Arian Foster, etc. were never thought of as super talents until they consistently produced on the field.
If a player can crack the roster of any given NFL roster, he has the minimum talent prerequisite to play in the league. He has the minimum physical attributes to play in the league. That minimum isn't chump change. All of these players, to a certain degree, have passed the initial test. Great players can be made when the minimum physical/talent criteria has been met. This is where we discover the talents of positional coaches. Only after player development will the media hype machine blow players out of proportion and have us scratching our collective heads when the team eventually parts ways with a "big name" player.
Credit must be given to the staff for fitting players into their scheme and fitting their scheme to their players. Credit for teaching technique. Credit for teaching situational awareness.
The salary cap prohibits teams from loading superstars into each and every position. Hence, one could point to any given roster and say that a given team is stronger in a specific area than another. For that reason, one can't judge a team by specific player groups. One can only judge a team as a comprehensive unit and as Bill Parcells used to say, "You are what your record says you are".
