Grading Pete Carroll's performance for 2015 season

Every morning, we'll round up local and national Seattle Seahawks-related links.

Greg Rajan of The Houston Chronicle hands out grades to all 32 NFL coaches. He gives Pete Carroll a B:

A horrible first half in the divisional round at Carolina ensured the Seahawks wouldn't go to their third straight Super Bowl, but Carroll did another good job leading the team despite injuries to RB Marshawn Lynch and TE Jimmy Graham. Now, if he could only erase his disastrous decision to pass on the goal line at the end of last year's Super Bowl loss to the Patriots.

A yacht owned by Seahawks owner Paul Allen destroyed reef in the Cayman Islands, per a report from the Cayman News Service:

An anchor chain on the 300-foot mega-yacht, the MV Tatoosh, owned by billionaire Paul Allen, has destroyed almost 14,000 sq.ft of reef in the West Bay replenishment zone, the Department of Environment confirmed following a survey of the area. DoE officials said more than 80% of the coral in the area has been damaged by the luxury boat’s chain. Local divers conducted an in-water survey of the coral reef damage last week and the DoE expects to publish the detail findings next week.

Bob Condotta of The Seattle Times looks at the offseason plan for the Seahawks' special teams unit:

The Seahawks have had the same kicking battery -- Ryan, who is also the holder, Gresham and Hauschka -- since 2011.

But that could change this offseason, as Ryan is an unrestricted free agent. He said he wants to return but added he would consider other offers, and the Seahawks could go with a younger, cheaper replacement.
