Where does one go to view the hardest hits of college football in 2012?

There isn't a single, centralized repository for "the hardest hits" of college football from 2012. Highlight reels and compilations varied across different sports networks (ESPN, etc.) and YouTube channels at the time. Many of these videos may no longer be easily accessible due to changes in online platforms and copyright issues.

To try and find some of these highlights, you could try the following:

* Searching YouTube: Use search terms like "2012 college football hardest hits," "best college football hits 2012," or specific team names combined with "hardest hits." You'll likely find various user-uploaded compilations, but the quality and accuracy of these can vary.

* Searching ESPN's online archives: ESPN's website may have some archived highlight reels from that season, though accessing them might be challenging.

* Checking other sports news websites: Sites like Fox Sports, CBS Sports, etc., may have archived video content from 2012.

Keep in mind that what constitutes a "hardest hit" is subjective, and what was considered a highlight reel then might not be seen that way now with increased awareness of concussion risks.
