I tip my hat for 25 years of work for the Vols, but I also admit I won't remember almost anything he called on the radio over those 25 years. All these years, but almost nothing memorable comes to mind. A very television oriented broadcaster in that respect - benign and in the background. Never distracting, but also almost never impactful.
Wilkerson is a great voice for radio. Not sure where he is or what he wants to do, obviously. Might like his current gig. Basketball-wise, Steve Hamer does a great job on TV, and I suspect he could also do very well on radio - or TV for that matter. Could be a good name to look at.
Whoever they pick, I hope they display a continuing commitment to professionalism a la John Ward - with just the right amount of Vol-colored commentary. Again, just like John Ward. I've listened to some of the other people in the SEC, and they're often unabashed emotional homers. Could do without that. Ward is the standard. I hope UT aims for that standard.
