He's by far the highest risk of any of the candidates available. No track record of success, late bloomer, pending UFA, playing in a low pressure environment on that a team that's just happy to be playing meaningful games on the back half of the schedule, even the career best season he is having isn't all that impressive.
These types of guys pop up every few years and get a few teams interested(Husso and Korpisalo, even Campbell kind of qualifies as some recent examples), they rarely pan out and usually fall back to irrelevancy by the next season after someone bets on them.
