I agree with almost all of this.
My biggest thing is I wish they would just go to more straight ahead reporting and less over the top yuk-yuk crap by the 'personalities' trying so hard to be 'entertaining'. There are some Sportscenter anchor teams I literally cannot watch - just give me the highlights and introduce some stories - so many of them with their ridiculous non-stop senseless 'banter' - god shut up. The classic old school Sportcenter guys knew the nuance of how to incorporate humor and commentary into the highlight/story without overtaking it - today it's mostly just idiotic, forced, unnecessary conversation between two nitwits,
Semi-related - I am so thankful that NFL Network has gone back to just straight ahead highlight show with single host. For some reason for a while the thing that was in vogue was having 4 ex-players nonsensically grunting and babbling over the top of the highlight - I absolutely could not stand that. It was like they wre told - "OK - when the highlight is running just make noises - that makes it so much more entertaining" How clueless are the people producing some of this crap.
