A look at the top under-the-radar move made by each NFC West team thus far this offseason:
Arizona Cardinals: A soft market for cornerbacks helped the Cardinals sign former San Diego Chargers starter Antoine Cason to a one-year, $1.5 million contract. Scouts Inc. gave Cason a 79 grade, tied with Chris Gamble, Brent Grimes, DeAngelo Hall and Quentin Jammer for highest among corners on the market this offseason. Arizona has rotated corners through its lineup with moderate success in recent seasons. There's no sense in overpaying when Patrick Peterson is anchoring the other side as a top-five overall selection. Cason has good size at 6-foot-1 and 195 pounds. He is on the younger side (turns 27 in July). He has never missed a game in five NFL seasons. He has started 45 of 48 games the past three years. Cason should provide an upgrade from 2012 starter William Gay.
St. Louis Rams: The Rams made waves by signing Jake Long and Jared Cook to deals with a combined $35 million in guaranteed money. Their move to bring back defensive end William Hayes on a three-year deal was important, too, even though it went under the radar. St. Louis led the NFL in sacks last season. Hayes had seven of them while playing 34.2 percent of the defensive snaps. He combines with Chris Long (11.5 sacks in 2012) and Robert Quinn (10.5) to give St. Louis a strong pass-rushing combination at defensive end.
San Francisco 49ers: Glenn Dorsey is too big to go under the radar, but anyone familiar with his time in Kansas City wouldn't think much of his signing in San Francisco. The 49ers seem to have big plans for Dorsey, however. They gave him a modest deal totaling $6 million over two seasons, a reflection of how far Dorsey's stock has fallen since the Chiefs made him the fifth overall choice in 2008. Dorsey wasn't to blame for the scheme change in Kansas City that made him less valuable to the defense. The 49ers run a base 3-4 defense that wouldn't seem to suit Dorsey's strengths as an up-the-field tackle, at least on the surface. I do think San Francisco has a specific role in mind for Dorsey, increasing the chances he makes a positive impact as a low-cost player with obvious talent.
Seattle Seahawks: The Seahawks made high-profile moves almost exclusively this offseason. They landed Percy Harvin, Cliff Avril and Michael Bennett before trading away quarterback Matt Flynn. There isn't much from which to choose in the under-the-radar category. Defensive tackle Tony McDaniel, signed from the Miami Dolphins as a cheaper alternative to Alan Branch, will have to suffice. McDaniel has been mostly a backup and rotational player during his seven NFL seasons. "He has great length with good power and plays with good pad level," Scouts Inc. wrote in its review of him. "He isn't a quick-twitch athlete and is inconsistent to get off blocks and show range to the pile. He has limited pass-rush skills and hasn't made great progress given his time in the NFL." How's that for under the radar?
