I run 3-4 with them. Here is how i set up my depth chart with the Titans
QB - Vince Young
HB - CJ2K, Ringer, Blount (But if its a running situation and CJ is out of the game, i will use Blount over Ringer)
WR - Britt, Washington, Gage, Williams, Hawkins
TE - Scaife, Stevens, Cook (For run blocking purposes)
LE - Ford
RE - Morgan
DT - Brown, Haye, Jones
LOLB - Thornton
MLB - Tulloch, McRath (the ROLB, hes pretty sick and a nice guy to put in if your using 3-4)
ROLB - Witherspoon
CB - Finnegan, Hill, McCourty, Verner
Hope this helps bro.
