I get all that about the recruiting aspect of the 3-4 but I'm talking about now, not the future. How many times, in an open field pursuit situation, have we seen our LBs and DBs 'containing ' when WHAM! here comes old Ed with his hair on fire to make the tackle.
I'm not saying our LB play is bad, I'm saying moving Ed to LB would make him so much more effective. 3-4 or 4-3 doesn't matter to me.
