> However, people love highlight reels. That's why Sportscenter is so huge.

Which is rapidly being replaced (to some degree) with things like twitter, instagram, snapchat, subreddits, streamable, and other social media/video streaming websites.

It takes next to no time or effort for somebody to roughly cut a highlight and post it to social media. Meanwhile ESPN sees diminishing returns polishing various replays and putting it in a half hour program that repeats 6+ times every morning. It's to the point every team/league even has their own social media accounts, and post the best highlights themselves. If I can see the major highlights directly from NFL's instagram account, why bother waiting halfway through sportcenter to (maybe) catch the right segment?
