Good to hear. Very solid 3rd pair RD. If we get Sauer back some time this season our D corps has to be considered the best in the league, at least on paper. Don't expect him to be re-signed with the rest of the 2014 UFA crew, but that's not much of an issue.
Offer sheet compensation is determined by the contract divided by the years, but that yearly value cannot exceed 5 years. So a team doesn't have to offer $7M per year for a team to get 4 1st round picks. A 8 year, $40M deal is $5M per year on the contract, but divided by 5 the compensation is $8m, and would be 4 1st rounders.
Great news, the lineup is shaping up. I don't think he comes as cheap as many of you seem to think though. With arbitration coming up, comparing him with other d-men in similar age and comparable stats, I don't see it being below 1,5 per. Playing it safe, I'm betting somewhere between 1,5 and 2,0. Either way, glad to see him back!
