Kornilov was killed early on in the Russian Civil War, but he would have been a good unifying figurehead.
1. He was winning victories against the Germans very late in the war.
2. He restored discipline in the army.
3. There is the Kornilov Affair, which he could "spin" as having seen the Bolshevik threat to Kerensky before Kerensky did, only to end up being sacked and jailed as a result of a misunderstanding.
