Tony Sparano might have found the key to help a very weak interior offensive line. Unfortunately, he didn't make the change until Week 16 when he moved OLG Richie Incognito to center in place of Joe Berger. Incognito, who will be a free agent at the end of the season, came into the league as a center and has been one of the Dolphins' few bright spots among those who have shuffled through the interior of the O-line. He filled in for an injured Berger in Week 11, then, in his Week 16 start, held his own against Lions DT Ndamukong Suh. "Richie is a powerful guy in there so he can negate power, and that's a good thing from that position," Sparano said. The way we hear it, the 'Fins might choose to re-sign Incognito as a center for '11. Weakness at guard and center is a big reason why Miami's rushing game went from a 4.4 per carry in 2009 to 3.7 in 2010.
