OK let's really get technical, the DTs in the 4-3 have developed into a two separate positions, not like the Bob Lilly Jethro Pugh days, the current 4-3 has a UT or undertackle, Okoye plays that position. The UT is expected to be a penetrate and disruptor.
The other tackle is know as the NT, that is the big guy that ties up blockers, allowing the MIKE and SAM to run free to the play. Okam and Robinson have the bodies to be this type player.
Few team try to play with 2 under tackles, the Texans did this last season with TJ and Okoye playing together. Also few teams are able to play with two nose tackles due to the lack of quality big men. The Old Ravens did this with Pro Bowl defensive tackle Sam Adams and veteran Tony Siragusa.
The two NTs is usually more successful than the two UT.
