Here is Boston Bruins general manager Peter Chiarelli’s explanation for acquiring forward Patrick Eaves from Carolina for defenseman Aaron Ward and then buying out the former Boston College star. Eaves is entering the second year of a three-year deal that paid him $1.1 million last year and was scheduled to pay him $1.4 million this season and$1.7 next year.

“Because the contract is structured with escalating salaries, we actually get a positive credit to our cap next year in the amount of $41,000,” said Chiarelli, who noted that because Eaves is younger than 26, the buyout is for one-third the value of the deal.

So if Eaves isn’t claimed on waivers, he will be a slight cap hit (around $258,000) for Boston this year and then give the Bruins more room next season.
