Helman is ok with me. Of course, you gotta keep in mind the goal of the whole DC.com shows, is to draw subscribers, so its mostly entertainment not high level football. So, out of the personalities of those shows, he's one of the least irritating to me.
Broaddus tends to irritate me because if you are paid to write or speak, you need to work on that skill. He interrupts others yeah, but what is really odd is that he will interrupt his own dialog and not complete sentences. He actually interrupts himself! yeah he's a former scout. yeah he has a super bowl ring. yadda yadda.
And while Nick Eatman has written books, and provides good insights (he's been wanting upgrade at safety and speed at WR for years), the attempts at "inside jokes" with his boss Derek Eagleton while on the air - the little muttered comments - attempts at looking witty - all that I can do without, and is very annoying to this listener. Get a room.
So, with all these odd personalities that don't come across well to audiences, Helman comes across as the most palatable like he's the only one I'd want to hang out with for a beer.
all that said, I'd totally suck if I had to do that job, so whatever!
