Because they are trying to get rid of their Sunday JetBlue* third jerseys.
That Sunday will be the last time the team wears them as, after three seasons, the Tampa Bay Rays look will be retired.
And, those jerseys will definitely be collector items.
I've been told the Panthers will not have a third jersey next season but there is a likelyhood they could have one by the 2013-14 season. Expect a dark blue jersey with a different Cat-In-A-Circle logo. Or perhaps the Sunshine/Palm Tree/Hockey Stick logo.
(*) -- So why do we call these jerseys the 'JetBlues?'
Well, word is Michael Yormark was one of the few proponents of this color scheme and brought it in to help lure the discount airline to become a major sponsor.
If that was indeed the thought, it worked. JetBlue is a team partner to this day. I have never gotten Yormark to confirm this story, but I have heard it from a good number of people. So, whatever.
In the summer of 2010, the Panthers had changed everything to those colors and it looked like the team was going to go to those colors exclusively for the 2011-12 season.
Only Dale Tallon, Mike Santos and Bill Torrey hated the look and refused to wear anything with the Cat-In-A-Circle logo on it. They quickly made it known that they hated the blue look and the Panthers quietly started phasing it out.
Then loudly splashed back with the 'We See Red' campaign when it was obvious the blue was out.
