CINCINNATI — No regular-season game in recent Bengals history has had any more meaning than the one with Baltimore Saturday. And I’m not just talking about what could occur on the field, but also with what will be happening in the stands at sold-out Paul Brown Stadium for some 40 children from the St. Monica’s Recreation Center in the Lincoln Heights area of Cincinnati.That’s all because of Domata Peko, the 322-pound defensive tackle who not only will be trying to prevent anything positive happening for the Ravens offense, but at the same time making sure nothing but good happens for all those youngsters, many of whom are in need.
