TSN 1050 already has their Morning Show (First Up) running from 6-10am, so it wouldn't surprise me to see 1050 follow 1040's lead, and have shows running from 6-10am, 10am-2pm, and 2-6pm. While I don't listen to 1050 as much as I used to, I think the American content during the day makes it worse for them, and this solution is much better than their current setup IMO.
It wouldn't surprise me once McCown retires to see Sportsnet go with a similar programming schedule, and have Tim & Sid take over for McCown's slot.
