Base 5-2 puts five defensive linemen (two DTs and three DEs), two linebackers, and four defensive backs on the field, which is the heaviest front you can field without going goal line. That extra body up front lets you two-gap the interior and set hard edges without asking linebackers to fill, so run fits stay clean against 21 and 12 personnel. Offenses that see this look have to either check into empty and spread you out to expose the two-linebacker second level, or accept negative-leverage runs into a loaded box, and the alignment shows up across 5-2 Normal, 3-4 Bear, Bear 46, Tite, and the 4-3 Leo fronts where a DE plays the stand-up rusher role.
