NFL team patterns

[Breezed]

Good morning KH.

Does anyone know if there is a collective place/book to get/buy knit/crochet patterns for NFL teams? I have been looking everywhere for a Chicago Bears afghan pattern, and the only one on Ravelry doesn't connect to instructions/chart. I messaged the user that made it but haven't received a reply yet. I know there is a way to copy the logo or whatever I want to graph paper, but unfortunately I'm not experienced enough to know how to translate that into a pattern for an afghan. I don't know number of stitches, size, nothing. I just don't get it, even though I've seen it explained a few times.
Thanks for taking the time.
