I happened to read the Cubs MLB board and they were all praising him for the dive. They were talking about how courageous and balls out he is. They even went to so far to say that he was the best team player on the field.
Correct me if i'm wrong but i can remember Frank and Jr having a grand old time standing on first base together almost every game. Constant chitter chatter and smiles. I always thought they were pretty good friends, no?
