The NFL is a passing league, and teams are looking for more and more center field-type safeties to combat that (think Earl Thomas). Traditional strong safeties can get undervalued, as T.J. Ward was on the free agent market this offseason.
Deone Bucannon is one prospect who could slip in the draft because of this trend. The former Washington State safety is a load at 6'1", 211 pounds, and he packs a punch to match. He's a physical player who has a knack for creating turnovers, knowing when to go for the ball while tackling and picking off six passes in 2013.
The Colts are almost certainly going to look to draft a safety early, according to coach Chuck Pagano, and the team sent secondary coach Mike Gillhamer to Bucannon's pro day. With the team using LaRon Landry as a free safety, Bucannon is a player that they could see as a long-term partner.
Bucannon had a solid Senior Bowl week and has all the physical attributes of a playmaker, but on film I see a slower Landry. Bucannon is a big hitter but can lunge and miss as well, and has liabilities in both zone and man coverage. I see him as a very possible option for Indianapolis, but I wouldn't be in favor in the early rounds.
