There isn't an eclipse or anything, but for nearly an hour today two potential Hall-of-Famers in football and baseball share Paul Brown Stadium. As Pro Bowl running back Corey Dillon takes a break in his daily workout, he greets Reds center-fielder Ken Griffey Jr. on his way to use the hydrotherapy equipment in the Bengals' training room. Bengals President Mike Brown, a Reds' fan who keeps up with the team daily, is glad to hear his underwater treadmill is making waves for The Cincinnati Kid. "His medical people thought our pool could help," Brown says today of Griffey's knee injury.
