Three thoughts as training camps open around the NFL:
One thing I'm certain of: Free-agent addition Jason Jones will fit much better at defensive tackle in Seattle than he did as a defensive end with Tennessee last season. The pass rush should improve as a result. Jones' addition on a one-year contract holds promise because the Seahawks seem excited about him. The team's leadership has been right on just about every defensive player it has targeted by trade (Chris Clemons), the draft (see the secondary in particular), unrestricted free agency (Alan Branch), street free agency (Brandon Browner) and position changes (Red Bryant).
Jones had a career-low three sacks for Tennessee last season. That matched the total for Anthony Hargrove, the player Jones is replacing in Seattle. Doubling that total seems to be a reasonable expectation for Jones if all goes to plan.
One thing that might happen: The confidence Seattle has exhibited in its young receivers could prove too optimistic. I'm going to have it both ways on this one. A month ago, I pointed to receiver as a position where the Seahawks might have "hidden treasure" on their roster. That could be the case, but some skepticism appears warranted. Seattle has so far proven more adept at building on defense than on offense.
Mike Williams' recent release left the team with a roster spot for a veteran receiver heading toward training camp. Antonio Bryant, who participated in minicamp practices on a tryout basis last month, could get another shot. The team needs Sidney Rice in particular to become more durable. The same is true to a lesser extent for Kris Durham. Doug Baldwin's presence gives the team a proven target from the slot and on third down. Golden Tate appears on the upswing. Ricardo Lockette's blazing speed intrigues. There are still quite a few variables and unknowns at the position.
One thing we won't see: The offensive line coach Pete Carroll and general manager John Schneider envisioned when the team used a 2011 first-round draft choice for tackle James Carpenter. The team expects Carpenter to miss training camp and open the season on the physically unable to perform list following surgery to repair a serious knee injury suffered last season. John Moffitt, a third-round choice in 2011, is also returning from knee surgery. Left tackle Russell Okung, the sixth overall choice in 2010, is returning from surgery to repair a torn pectoral.
Breno Giacomini has proven to be more than adequate as Carpenter's replacement, to the point that he could remain at right tackle for the long term. Deuce Lutui's addition helps depth. However, another significant injury to Okung would set back the line tremendously.
