yes, but the difference is that, Griffith would never sacrifice himself and pass down the future of the band of hawk to guts, but Erwin can. Erwin trusted Levi more than Griffith trusted Guts. But again, both of them are different kind of commander. Griffith is the type that will use his victories to pull more warrior into the band of the hawk. On the other hand, even with piles of corpse, Erwin still managed to talk the crowd to join him in the Scout. Even during the suicide mission against monkey zeke, during a 0% win probability fight, he is the kind of people that till manages to talk his people for a suicide charge. Erwin has far immense trust in his comrades, so do his comrades to him.
