As a restricted free agent, he would not have walked away for nothing.
RFA compensation for this year kicks on only if the cap hit is above $1,034,249. I can't see a team offering a guy with 26 games in the NHL more than that, and I sure hope Ottawa signed him for a cap hit that is under that.
The criteria for RFA draft pick compensation in 2011-12 is as follows:
$1,034,249 annual cap hit or less: No compensation
$1,034,249 $1,567,043: Third-round pick
$1,567,043 $3,134,088: Second-round pick
$3,134,088 $4,701,131: First and third-round pick
$4,701,131 $6,268,175: First, second and third-round pick
$6,268,175 $7,835,219: Two first-round picks, a second and third
$7,835,219 and higher: Four first-round picks
