I believe a player has to be qualified before he can be taken to arbitration. If the player is not qualified, and if the two sides don't negotiate a contract on their own, then the player walks as a UFA.
So the Avs better hope they can repair their relationship with ROR.
Otherwise they will likely be forced to give him a one-year, 6.5M qualifying offer (which ROR would likely sign, as otherwise he goes to an arbitrator who will likely award him less) or let him walk.
Some restricted free agents are eligible for salary arbitration, if the following conditions are met
For players signing their entry-level contract at age 18 or 19 (but who will not turn 20 in the same calendar year that the entry-level contract was signed), a season of professional experience is at least 10 NHL games played, and at least four such seasons must be accrued for arbitration eligibility.
For players signing their entry-level contract at age 20 (or who will turn 20 in the same year that the entry-level contract is signed), a season of professional experience is at least 10 professional (non-collegiate) games played, and at least four such seasons must be accrued for arbitration eligibility.
For players signing their entry-level contract at age 21 or older, arbitration eligibility comes at the expiration of a player's first contract.
A team can only take a player to arbitration one time in his career, while a player may elect arbitration as many times as possible, provided that a qualifying offer has been made. After a qualifying offer is made, an eligible player can elect to go through the arbitration process, where the team and the player each make an argument for a certain contract size. An independent arbiter hears the arguments and decides on a fair contract amount. If the player has elected arbitration, and the award is more than $3,500,000 (from 2005-2012, the threshold was $1,042,173), a team has 48 hours to "walk away" from the arbitration award, making the player an unrestricted free agent. If the team has elected arbitration, the arbitrator's award is binding regardless of the amount.
If a restricted free agent does not sign with an NHL club by December 1 of that year, that player is declared ineligible to play in the NHL until the following season.http://en.wikipedia....ary_arbitration
