I'm not saying this is why they are doing it, however, follow me here...
In July 2016, there was an opposition filed to the USPTO (https://trademarks.justia.com/859/34/cooper-85934700.html). I'm guessing that someone challenged Bauer's ownership of the trademark for not having it used in commerce and their attorneys went into motion.
A year later, the opposition was mysteriously dropped, and Bauer has since asked the USPTO for extensions, to the tune of a 5th extension filed and granted in March of this year.
So, my guess is USPTO told Bauer to either shit or get off the pot, and this offering is them getting off the pot.
BTW, this is why the NHL, for many years, has kept their top past team logos as offerings (i.e. NY Americans, Hartford Whalers, Minnesota North Stars, Quebec Nordiques) on nhl.com.
Anyhow, carry on.
