SAN JOSE, Calif. Becky Sauerbrunn USA Jersey . -- San Jose Sharks general manager Doug Wilson is wasting no time making changes after perhaps his teams most crushing playoff collapse. Wilson said Thursday that he told pending unrestricted free agent defenceman Dan Boyle that he will not be re-signed, informed unproductive forward Marty Havlat that he will not be back next season and moved top-line wing Brent Burns back to defence after spending more than a year as a forward on captain Joe Thorntons line. These changes all come two weeks after the Sharks became the fourth team in NHL history to lose a best-of-seven series after winning the first three games. Wilson spent the past two weeks meeting with coaches and players to help determine what went wrong in the final four games against Los Angeles and how to get a team that has been one of the best in the regular season the past decade over the playoff hump. "You want to be careful not to change too many things, but you better be really careful that youre not just avoiding what really needs to take place," Wilson said. "Theres two sides to that. I think what we need to do is much more drastic than just putting a Band-aide on it." Wilson said the moves this off-season will build on the moves made at the trade deadline in 2013, when the Sharks dealt away Ryane Clowe, Douglas Murray and Michal Handzus in an effort to become a faster and younger team. Those moves helped San Jose make it all the way to Game 7 of the second round before losing to Los Angeles a year ago and Wilson said the team is about two-thirds of the way to completing the overhaul. The team appeared closer than that after winning the first three games against the Kings but was unable to close the series out. Wilson blamed the collapse on allowing too-many odd-man rushes, a power play that went scoreless on its last 16 chances, a lack of effort in Game 5 and a late-game collapse in Game 6 after a disputed goal was allowed. "Our relationship with our fans has been strained and weve got to go and re-earn that trust," Wilson said. Boyle has been a key part of the Sharks since being acquired in a trade from Tampa Bay in July 2008. His 68 goals and 201 assists in six seasons make him the career leader in both categories in franchise history and he has been a staple on the power-play unit. He will be replaced on the blue line by Burns, who spent his first year and a half in San Jose on defence before making the move to forward in March 2013. Burns had a career-high 22 goals this season along with 26 assists as he teamed with Thornton on a physically imposing line that controlled play for much of the season. But Wilson said he is needed now on defence and compared Burns potential impact there to Montreals P.K. Subban, Winnipegs Dustin Byfuglien and Los Angeles Drew Doughty. "When you take a look at that type of dynamic on the back end, guys that move the puck up, shoot the puck on the power play, it creates a tough matchup," Wilson said. "When he was originally moved up to forward, it was because of an injury. He was coming back and he was having trouble with certain parts of his skating." Havlat scored 27 goals in three injury-plagued seasons with San Jose after being acquired from Minnesota in a trade for Dany Heatley. Havlat fell out of favour with the coaching staff and was a healthy scratch in six of seven playoff games. He is owed $6 million in the final year of his contract and will either be bought out or dealt. Wilson would not divulge what other changes he had planned but did say some of those could come in the teams player leadership. Boyle must be replaced as an alternate captain and Wilson said he expected some of the younger core, including forwards Logan Couture and Joe Pavelski and defenceman Marc-Edouard Vlasic, to possibly take a bigger role. "I expect our young players to take this as probably one of the great extreme learning moments to say, You know what? Thats not happening again," Wilson said. NOTES: Assistant coach Larry Robinson will be back but could have an expanded role that includes some front-office duties. ... Wilson said talks have already begun to keep backup G Alex Stalock, who can be an unrestricted free agent. ... Pavelski (shoulder) and F Raffi Torres (knee) had operations after the season.

The left-hander, who hasnt thrown in a week because of stiffness in his neck and back, just hopes things are different from last year. He was the opening day starter then, but made only one more start. "Kind of trade-off from last year," Harrison said Sunday. "Only making two and miss 30, and miss two and make 30, that would be nice. Even though Harrison is feeling much better after switching beds, he was still returning to Texas to be examined by the specialist who did both operations last year for a herniated disk in his lower back. "I think at this stage, based upon the initial symptoms that he reported, we just wanted to make sure were all clear before we ramp up again," Rangers assistant general manager Thad Levine said. Harrison had also been scheduled to throw live batting practice last Tuesday and wanted to pitch, but the Rangers held him out of that as a precaution because of neck stiffness. Two days later, he was scratched again from a throwing session with stiffness in his back. An MRI showed no immediate cause for concern, but the Rangers scheduled an appointment with Dr. Drew Dossett, who wasnt available until Monday because he was at the NFL combine. "I think for sure the bed was an issue. Since Ive gotten out of that bed and switched bbeds I havent had any issues," Harrison said. Megan Rapinoe Jersey. "Everybody usually feels sore the first couple of days just getting back acclimated to running around out there." Harrison won 18 games and was an All-Star in 2012, then got a $55 million, five-year contract. He had never had any back issues before last spring, and still made his first two scheduled starts. After going 0-2 with an 8.44 ERA, Harrison got two epidural injections and a second opinion before two operations in a matter of weeks. Harrison threw for a couple of months with no problems before camp this year, so he expect to have to completely start over when he is cleared by the Rangers to throw again. He hopes hes able to make his season debut no later than the middle of April. "This little setback set them on high alert and theyre probably going to slow it down a little bit," he said. "Which I hate because going through a healthy off-season and being ready to go its tough to get shut down. But its early." Levine said the Rangers put a lot more value on having Harrison healthy for the stretch drive late in the season than a start in April. "Were not panicking," manager Ron Washington said. "He is feeling better. Hes not feeling what caused us to shut him down anymore, so hopefully when the doctor sees him, it was just was some residual from everything he had done." ' ' '
