Both Jaguar and Ajax have made blunders, but on completely opposite sides of the spectrum. The new Jaguar logo is abysmal, absolutely shocking stuff — not much more to say.

Ajax, on the other hand, has gone from a fairly decent crest (minimalist, but still honoring what came before) to a mural/illustration. The classic design they returned to is not adequate as a crest, insignia, or logo. It's really not good as anything except maybe as a side of a coin. They'll have to rebrand eventually once they realize what a nightmare their new (old) design is to incorporate into any environment and depending on who's in charge at that time, the result maybe something as bad as the Jaguar or Juventus rebrands.
