GENEVA – Big-ticket sports broadcasts inevitably include references to announcers’ off-air interactions.

Jim Nantz and Phil Simms of CBS meet with a football coach at the team hotel, or ESPN’s Dan Shulman spots a bulky power forward traipsing across a college quad.

In their first season together on Geneva’s online Vikings Sports Network, Jack Housenga and Kevin McCarthy have also channeled what they know during boys and girls basketball games. For the longtime friends and Geneva juniors, that often amounts to cafeteria conversations and hallway head-nods.
