Welcome to the Q&A Forum

I agree with John and Steven. We manage a number of sports blogs, and I have my content writers link back to old posts using new posts.  If there is a legitimate reason to link to the old post then go for it.  For a local music blog, I frequently write content that has no expiration date.  For example, I may post all summer about bands coming to town, or write reviews, but every few posts I might write a “top five music clubs in town” post. Those posts are relevant to my blog, they can be linked back to at a later date, and have the chance of picking up traffic at any time (depending on the search.)  Analytics will also tell you which posts are getting traffic, no matter how old the post may be.  That should give you a clue to what stays relevant.

Our company gets inbound links from news websites that write stories about upcoming sporting events. The links we get are pointing to our event / ticket inventory pages on our commerce site. Once the event has passed, that event page is basically a dead page that shows no ticket inventory, and has no content.  Also, each “event” page on our site has a unique url, since it’s an event that will eventually expire, as the game gets played, or the event has passed.

Example of a url that a news site would link to: mysite.com/tickets/soldier-field/t7493325/nfc-divisional-home-game-chicago bears-vs-tbd-tickets.aspx

Would there be any negative ramifications if I set up a 301 from the dead event page to another page on our site, one that is still somewhat related to the product in question, a landing page with content related to the team that just played, or venue they play in all season.

Example, I would 301 to: mysite.com/venue/soldier-field tickets.aspx (This would be a live page that never expires.)

I don’t know if that’s manipulating things a bit too much.

I agree with Josh here.  With a bit of work on your "About  Us" page, it might pop up when customers search for your brand.  We made sure to have a good title, proper NAP, and a well written business description, with photos of our office.  It was worth the small effort.

I agree.  When I need a lift for my own content creation, and perhaps to recruit others to write, I head over to the department in question, to take some time to brainstorm.  Most times, my coworkers are happy to add some ideas. More often than not, I can get someone to write something up for me. These brainstorming sessions also help me get out of my content rut.
