It’s a savvy acquisition for Yahoo, one that delivers a pre-existing and very local audience to Yahoo Sports, which is battling it out with ESPN.com and other rivals for the desirable college-sports-fan demographic. And of course, it helps that Rivals.com is actually making money–about $22 million or so a year. That said, it’s not really the sort of major acquisition (read: Facebook) that might make up for the two big bungled acquisition chances–YouTube and DoubleClick–that allowed Google to take such a commanding business lead.
