 The OLBs often line up closer to the line of scrimmage than the ILBs, but may also be positioned at the same depth or deeper in coverage than the ILBs (though this is somewhat rare).There are two types of ILB's, the Mike (for strong side) and the Will (for weak side).The Will typically is the more athletic linebacker, who can blitz, drop into coverage, play the run, and "spy" the quarterback.
