Buying a jersey is not always a straightforward experience. For the Denver Broncos, or any football jersey really, the process of going through with purchasing a player's jersey has to be well thought out.
A full-price jersey costs $100, not a small piece of merchandise or memorabilia for the majority of fans. Because of the high cost of a jersey, each purchase means the fan is investing substantially in a particular player.
To invest in a jersey, a player should be around for more than a season (nobody wants a $100 rental jersey these days) or a legacy player.
