When I evaluate potential 1-technique defensive tackles, I look for size, strength and quickness. They don't have to be extremely fast, but they should show some natural athletic ability and quickness to their game. Usually these prospects are great at stuffing the run, but they still need to have some pass rushing ability.
The 3-technique lines up between the guard and tackle and will shade over either side of the guard's shoulder. Most of the time the 3-technique will get a one-on-one matchup with the guard. Usually their job is to win that matchup and shoot the gap and get into the backfield. While the 1-technique needs to be large and strong, the 3-technique is usually lighter and quicker because their game is based off of speed. It's much harder to find the 3-technique because of the athleticism that is required to play the position.
When I evaluate potential 3-technique defensive tackles, I am looking for a good motor, quickness and pass rushing ability. Size isn't really a big issue because those other attributes are far more important to the success of an effective 3-technique tackle.

The 1-technique is a very important position on the defense, but I don't believe the Cowboys should be spending a first round pick to find a player who would probably be getting off the field on third down passing situations. It's a position that requires some pass rushing ability, but not as much as the 3-technique. Star Lotulelei is a unique player that can be a handful, so he would be worth the investment, but he's a potential top-five pick.
Hankins would be great
