Man, I'm always getting proven completely wrong lol.Please forgive my ignorance, but I was under the impression that they got new jerseys every season in the physical sense, and it's just the design gets updated periodically. I'm with you; I don't think a lineman's jersey could make it more than a season, if that. I'd love to hear from someone more in the know.
That reminds me: Do people remember those mesh tear-away jerseys from the late 80s early 90s? RBs must've gone through at least five per season.
Thanks for the info y'all. Although it does make me wonder, if they're getting brand new jerseys every year, why can't they get updated styles at the same time? It kind of makes even less sense now.
