One of the storylines of the draft was the teams making the transition to the 3-4 defense - Denver, Green Bay etc. Bill Belichick is a guy who obviously regards himself as someone who is 'ahead of the curve'. This makes me wonder when the Patriots will move away from the 3-4 and back to a 4-3 formation - or maybe something more (r)evolutionary. Teams like Pittsburgh and New England made a killing in the early part of this decade at draft time - being able to select so-called 'tweeners' for their OLB position in later rounds - due to the fact 4-3 teams didn't value them so highly. Now we see a shift on 2 fronts - opposition offenses figuring out the 3-4 and more teams moving to the 3-4 - the latter will surely only hasten the former. When does the 'tipping point' arrive whereby its more beneficial, and better value, to draft/recruit guys who fit the 4-3 better than the 3-4 - 2010, 2011? As noted by many draft day prognosticators - there are only so many 3-4 NT tackles out there. I realise that there is more than just a single 3-4 defence and that different guys suit different schemes better but, looking ahead, the playing field and talent base are going to become more stretched as time goes by. Any thoughts?
