True that to some degree. It goes both ways with Kimi and Vettel. They both better than what they are showing this year. Kimi can easily force his way to Ferrari' priority by race well to his true capability if he want but he rarely shown that so far this season. He is keeping up as their 2nd driver, but thats about it and its a massive understatement to Kimi's talent. Ferrari doesn't help either with their shitty tactic. They should be leading both championship by now.
In terms of tactical/driver cock-ups thus far.
Australia - Mercedes cocking up by miscalculating the pit window.
Bahrain - Ferrari cocking up a pitstop for Kimi, Mercedes possibly cocking up by not pushing hard enough as to allow Vettel to nurse his tires home for a win.
China - Mercedes possibly cocking up by not pitting Lewis - could've cost him a couple of positions. Vettel taken out by no fault of his own, on course for a finish ahead of Hamilton.
Baku - Vettel unlucky with the safety car, then cocking up what could have turned out to be the race win with attacking Bottas too aggressively. Mercedes unlucky with Bottas getting the puncture.
Spain - Possible Ferrari cock-up with pitting Vettel, allowing Max past him - can't remember excactly? Mercedes dominant either way.
Monaco - No one really cocking up except for Verstappen in quali. Red Bull simply faster on the day.
Canada - No one really cocking up, Mercedes forced into early Hamilton pitstop which let Ricciardo past him.
France - Vettel cocking up through his own fault. Mercedes flawless, Ferrari pretty flawless tactically as well all things considered, bringing Kimi home in 3rd even though he started on the ultras.
So, in essence, I'm not really sure Ferrari's "shitty" tactics are that much to blame. In my view, a couple of driver's mistakes from Vettel and the unlucky Verstappen take-out have cost him.
Lewis, for all the talk of him driving poorly, has pretty much maxed out his points in terms of what pace he had at every single weekend - made no big mistakes and made his opportunities count.
Vettel, in what seems the better car this season, hasn't, and pays the price.
I still imagine it'll be close. Austria should see Ferrari and Merc neck to neck, same with Silverstone, and in Hungary the Ferrari's should have the upper hand.
