Dolphins Talk With Incognito

       Richie Incognito, voted by his peers as the NFL's dirtiest player last season, made a free-agent visit to the Miami Dolphins on Monday. The Bengals and Colts also are after the controversial offensive guard, the source said, but he will make his first visit to South Florida in hopes of signing here. Incognito, 26, nearly joined the Dolphins in December, but they lost out on their waiver claim to the Bills, who were lower in the standings. Fined nearly six   figures for various on-field incidents so far in his brief NFL career, Incognito is a former third-round draft pick of the Rams. He has made 47 career NFL starts, including three to close out last season in Buffalo, but the Rams dismissed him after he had a run-in with coach Steve Spagnuolo during a Dec. 13 game against the Titans.
