Don Stevens is the voice of Amerks. He's been calling their games for 26 years, and while I'm not sure he'd want to leave the Amerks and announce elsewhere, I would LOVE if he took over when RJ decides to retire. Stevens is fantastic, in my opinion. SO much better than Sylvester, or really anyone the Sabres have auditioned so far.
I personally hope they find a diamond somewhere in North America that's no older than mid 30's. I would rather have a long lasting PxP guy (like RJ), than a guy who has the gig for 10-15 years and retires!
