A few highlights and lowlights from the 10 days of organized team activities for the Seattle Seahawks:

Best rookie draft choice: WR/KR Tyler Lockett. This guy is going to make an impact of punt and kickoff returns this season. He’s quick, confident and fundamentally way ahead of most rookies.

Best rookie free agent: RB Thomas Rawls. Hard to tell a lot without any actual tackling, but the Central Michigan product shows a lot of quickness and good instincts. He gets to the line of scrimmage in a hurry and seems to have an extra gear in the open field.

Worst ongoing discussion: The endless speculation over quarterback Russell Wilson’s contract status. Hopefully something will get resolved before training camp, but don’t hold your breath.

Best addition: Tight end Jimmy Graham, of course. In one OTA session last week, he had five TD catches in the red zone.

Best recovery: Strong safety Kam Chancellor and cornerback Richard Sherman. Surprisingly, both Legion of Boom stars were full participants in OTAs. Chancellor had a torn MCL in the Super Bowl and Sherman played with a torn elbow ligament. They both elected not to have surgery and seem to be OK.

Biggest mystery: What defensive end Michael Bennett and linebacker Bruce Irvin will do next. Bennett wants his contract reworked. Irvin is unhappy about the Seahawks deciding not to pick up the fifth-year option on his contract. Skipping voluntary OTAs is one thing, but will they show up for mandatory minicamp next week?

Worst news/best news: Defensive tackle Jesse Williams learning he has cancer and undergoing kidney surgery, but tweeting Thursday that he has been cleared to start working out again.
