2-5
In this variation of the 3-4, known also as the "3-4 eagle", the nose tackle is removed from play and in his place is an extra linebacker, who lines up on the line where the nose tackle would be, sometimes slightly behind where the nose tackle would be
So the difference is that in the 3-4 the NT has his hand on the ground. In the 2-5 it is a LB "where the NT would be" in a 2 pt stance.
And LOL using Wiki as your guide to football.
The reason for having 1 or 2 players lined up in a down position, and the rest standing either at the line or slightly off the line is to so OL/QB won't know which players are going to blitz and which ones are going to drop off and screw up the blocking scheme and/or confuse the QB.
