NFL free agency is a great way to plug holes in a team's roster and reinvigorate a fanbase. Seconds after ESPN reporter, Adam Schefter announces any trade, fans of all 32 teams can be seen on Twitter saying things like: “My team signed (insert name here)?! He was so underrated on his old team. Our coaching staff will turn him in to a Pro Bowler!“ Or on the flip-side, “Not a big loss. The (insert team's name) WAY overpaid for him. He wasn't even that good!“
As we have learned, relevancy is probably the number one factor when flipping cards. When a player is acquired via free agency or a trade, they immediately become a relevant talking point through local and national media.
As an example, earlier this offseason we saw that scenario play out in the Matthew Stafford card market almost immediately after he was traded from Detroit to Los Angeles. On January 23rd, his 2009 Topps Chrome PSA 10 was selling for around $300. He was traded on January 31st, and within two weeks, the same card was moving at around $1250.
The energy that sends fans to Twitter, excited to welcome their "free agent steal" (or so they are convinced), will also send folks to eBay to purchase their rookie cards. After all, if fans are convinced that the player was under-utilized and under-appreciated in his former city, investing in that card makes all the sense in the world, right?
Here is a list of my top 10 players that were available during this free agency period and why their cards might be a good buy:
