Not arguing but that has nothing to do with being over confident. I guarantee you the pats have a page ready also on case they win and modells has championship gear made for both teams
you're absolutely right, I'm sure this was was an honest mistake, they were probably testing the page and accidentally made it go live.
On a side note do you know what they do with the losing teams championship gear?
MLB used to require that they be destroyed but now most of the leagues donate them to overseas charity causes.
