Guyton, 26, made the Patriots’ roster as an undrafted free agent out of Georgia Tech in 2008. Guyton runs well for a 6-foot-3, 245-pound linebacker and flashed cover skills in New England, but struggled in nickel packages last season. The Patriots made little or no attempt to re-sign him.
The Dolphins are expected to run a base 4-3 defense under new coordinator Kevin Coyle. Guyton will compete for playing time at outside ‘backer.
