Cav to DQS is a great move. They are short a sprinter. Their number 3 guy, Hodeg, hasn’t been showing number 2 guy form. Under normal circumstances they bring in a high level sprinter to slot into that number 2 position, but they don’t want to make a move that looks like they are writing off Jakobsen. So they bring in Cav, who clearly isn’t a long term replacement for Jakobsen, who brings a load of publicity and, if anyone can get some of the old Cav back it’s them. Even if he fails completely, they get loads of media coverage for what is probably more or less zero money and on current form they wouldn‘t get much out of promoting Hodeg anyway, so there’s no real risk (sorry Alvaro fans, I like the guy but he’s not showing much).
From Cav’s point of view, well if he wants one last chance, he couldn’t get a better one than at DQS.
