I look at this thread question in two minds:
Have they peaked from a sponsored pro and tournament result standpoint?
Have they peaked in their approach as a company to market and push plastic?
From a sponsored pro standpoint, I think they have peaked and will be on the decline this year. On the FPO side they lost the best women's disc golfer of all time and no one can fill that void. Their remaining sponsored women were inconsistent at best last season and I don't except much next year. On the MPO side, they have been stagnant for a few years now. They haven't made a big move signing at all and have hit the peak with their current crop of players. Maybe one will win a DGPT, but I highly doubt any can win an NT. Lat64 and Westside have made the big signings that DD should be after as the flag shift brand. You could even argue once Uli, McBeth and Nikko left DD because they started making their own discs, that was the start of the sponsored pro decline (for MPO).
Have they peaked in their approach to market and sell plastic? Hard to know without seeing financials and my thoughts are pure speculation. I would say their marketing and push for younger golfers is working, the in your face social media has created a niche and their pros (though up and down) have cult followings. I think they need to reinvent themselves a little bit to stay competitive with Discraft and Innova long term. Or maybe they are fine with the volume of product they are pushing, Kansas is a cheap state to live/operate out of and I'm sure they are not hurting. I would say they haven't peaked in this sense quite yet, but are pretty darn close without changing their approach to match other companies.
It's hard to not be excited about what Discraft and Innova are doing. Hell, it's even going to be fun to watch Nikko at Westside. I don't share that same excitement for DD and find their marketing to be a little too much. I do think Robert and Bobby have great delivery in a podcast format - wish they could talk about stuff beyond DD. And I think Robert is a great live commentator.
And for those asking if Discraft previously peaked? I would say yes they did and then they did something about it. They changed owners, signed McBeth and other top pros, created new exciting discs and now got PP to do the same. That's the great thing about hitting yoir peak, once you start trending downward you can reinvent yourself to grow again. I don't see DD quite ready to do that.
