I only watched half of it but I too thought it was fairly boring.
I like Chuck and think he's a highlight even if the repeated fat/gambling/bad at golf jokes get stale. He actually asked a decent question to Brooks and Bryson when they switched to alt shot about playing with another players ball but Brooks and Bryson didn't really answer beyond "bro, we're good" and then "haha you said balls." Immelman is very good in his role at CBS, my favorie lead analyst, but I don't think he works as well in this type of non-serious setting. Feherty is whatever, I forgot he even existed. Honestly the perfect booth guy for this (and really, any golf) is Mickelson but I don't think that will ever happen.
Bubba was horrendous. It sounded like he was tryinig to read everything off a scrip, very deliberate delivery. No insight whatsoever. I think Colt Knost is kinda the guy for that role. He's experienced as an on-course reporter so he can handle setting up each shot but he's also got a relationship with the players and can bring out their personality when interacting with them.
I think in general it's just hard to make real golf exciting with 4 guys on the course. There's a ton of downtime and air to fill and you can't force good play.
