I got to thinking about the roster implications, of entertaining different defensive systems.  In simple math, if you have the players for a 3-4 and a 4-3, you´re keeping a set of 7 special skillset players for one system and a set of 7 special skillset palyers for the other system.  This is detrimental to establishing quality depth at every position.  I would much rather, you commit to a 3-4, designate 7 starters suited to it, and get the 7 best backups you can find.  In simple think that would mean you have 14 players who are suited to what´s expected of them as compared to 14 with a divisive, confusing skillset.  The way things are, it tells me the powers that be have settled for subpar if not possibly abysmal in trying to find the right combination.  This is catastrophe in the making.
