Analysis: Seymour was an exclusive rights free agent. The 6-foot-4, 305-pounder made his NFL debut last season after he was claimed by the Browns in August. After Pro Bowl center Alex Mack broke his left leg against Pittsburgh, John Greco and Nick McDonald both started before Seymour took over on Dec. 7 against Indianapolis. The 25-year-old held the job for three games before sustaining a hamstring injury against Carolina and sitting out the finale.
