Companies large and small have wasted no time finding college athletes for sponsorship deals, just weeks after the NCAA granted them the OK to do so.

Sports experts say this is only the beginning.  "The speed at which companies went after these athletes was shocking," Tim Derdenger, a sports marketing and branding expert and professor at Carnegie Mellon University, told CBS MoneyWatch. "I mean, I knew it was going to happen eventually, but we're only three weeks in."
