It does seem to take some time for kickers, especially Canadian ones, to come into their own (Lewis Ward being a notable exception). Lauther in Saskatchewan kicked for the Ticats five years ago and has been trying to get back to the CFL since; now, he is lights out. Medeiros has improved since his first stint in Toronto; both his and Pfeffer's punting have been superb; Medeiros has been better than Pfeffer with his placekicking but he seems to miss one makeable kick per game that ends up hurting the team. I do think that Medeiros and Pfeffer still have lots of potential to be all-star kickers though.
