While discussing Renteria on ESPN last night, Berman said "we know how he performs at the end of games from the '97 WS."

Hmmmm? Do we? Is that really enough to "know" from? If I had seen Berman do one Sportscenter 8 years ago, would I be right to say "we know he's too happy with his crappy nicknames, from that August '97 Sportcenter."

Well, in that case I would have been right, so that's a bad example.
