Yes, I heard that as well. TBH, I have not listed to DeBella in a while (mostly during commercial breaks from P&S). Not familiar with Steve, but I am sure it is the right choice from a financial standpoint and keeping the built in audience. The era of the local morning show with big names and big ad budgets are dwindling. MGK should be more about the music and the community.
DeBella's final show was very nice. Very well timed and didn't drag on making it a mess (i.e. Cheers cast on the Tonight show-dating myself). Good luck in retirement, hope he pops up occasionally for his excellent charity work.
