Here's what I posted in another thread regarding NBC's American TV commentary:
It's absurd how dumbed-down the commentary is for most of the races. Tonight I watched the TV broadcast after watching the Internet broadcast exclusively for like five days and I can hardly stand how uninformative and simplistic most of the analysis is. I'm not hating on the people so much as I'm sure they're doing what they're told, but there is nearly zero interesting context provided for most of the action and whenever there is a big in a race, it's just, "and here we have the start of the (event name), it's (big name), out of the block... there's (another top contender), but it's (big name)... And down the home straightaway! It's (big name). And there's the gold medal (said with little hype)."

I see someone in this thread beat me to a spot on Hammond impersonation.
The bottom line is Hanmond has his job because he has a great voice. I'm sure he works hard at what he does, but he just doesn't have the passion or the insightful, nuanced commentary for the sport. That can only come from, at minimum, several years of really loving track and field and it cannot be faked with a booming, epic voice (which he does have) or by reading some facts off notecards.
Given how long he has been commentating track, I would have thought he would have developed some of that love of the sport and sophisticated analytical ability, but it seems like he never will. Whether that's something inherent in him, lack of effort, or the result of directions coming down from the top ("keep it simple and just keep yelling about Bolt and whatever Americans are in the race!"), I have no idea, but I do hope a change is made for the sake of the sport. I think track would immediately impress and intrigue more people if they just let the Internet team take the reins.
