Now Ed Johnson is back and the Colts drafted Fili Moala and Terrance Talyor. Dawson played his rookie season at defensive end, where he backed up Dwight Freeney. Dawson will now compete with Marcus Howard for snaps when Freeney is out.
The Colts will still likely use Dawson at defensive tackle sometimes. They will probably use Dawson at end on obvious running downs. The Colts could even consider using Dawson as the starting end, and only use Freeney on passing downs.
