SANTA CLARA, Calif. -- The San Francisco 49ers' receiving group should be much deeper this season than it was last year.Steve Johnson, Brandon Lloyd and Bruce Ellington are all potential big contributors. Their additions could make it easy to forget Quinton Patton.But that might be a mistake.Despite the additions, Patton is very much in the mix for the 49ers. The 2013 second-round pick has had a nice training camp. He shined Monday in front of 10,000 fans at Levi's Stadium, making play after play.
