I'd wait another year. Usually rookie kickers struggle on kickoffs or struggle with field goals. So if you get a guy that does well on field goals, chances are he'll struggle on kickoffs. They'll probably get Folk's leg stronger and he'll have more endurance. Plus, he should be getting used to the lower kickoff tees and just overall knowing how to kickoff in the NFL, which is much different from when he was in college (they used to have huge tees and kickoffs from the 35 and it was easy to just swing as hard as they could and hit low line drives that were far into the end zone.).
