I didn't find Zorn to be monotonous or boring. I really enjoyed his input and his insight into the game as a former player and a former coach.
950 KJR has really stolen the morning time slot for me because they have Mike Holmgren on every week. I always tune in to listen. Granted, he is about 75% chat and 25% insight - but that 25% insight is 1000 times better than anything you get from the talking heads on ESPN and NFLN. It was fascinating listening to him talk about working with Bill Walsh, his Superbowl experiences, how he developed talent, what he thought about Manziel, etc. Every time he talks about the business of football, I learn something completely new and gain a much more profound respect for the depth of the pro game.
The same holds true with Jim Zorn. When he talks, he talks about the game from the perspective of both a highly successful former pro QB AND as a former coach. It's really incredible getting that perspective. I find his balanced mellow delivery makes it that much easier to listen to. He was on recently talking about the best moments in Seahawks history, and I was riveted listening to his opinions about playing in the Kingdome vs Clink, the Steve Largent hit on Harden, and Effren Herrerra and the old Seahawks running the fake FGs. Time flew by, and I found myself wanting more. It was especially hilarious listening to his response to that idiot who said NE had a better secondary. Just absolutely brilliant. The dry delivery, his chuckles, his words of caution to the writer, and his simple statement that "Well, one team has already proven themselves, and you're banking on another team getting all the luck going their way which just doesn't happen in the NFL".... simply brilliant.
The rest of the guys.... meh. Brock and Salk are good because together they have a really fun chemistry, but I don't tune into them to learn about the in-depth inside workings of the NFL. Jim Zorn and Mike Holmgren really bring that, and it makes for GREAT listening.
