Larry Holmes fought bums for the most of it.

Holmes also prevented a few contenders from rising. Berbick was 18-1 when Larry beat him. Carl Williams was considered a top HW at the time undefeated. I remember he sold himself rather well The Truth! Nice jab. But Holmes took his '0'As well as Renaldo Snipes '0' who both IMO would have held titles had Larry not been there.
No fault he took on Spinks who kept himself in contentions with his win over Evangelistsa, but I agree neither fighter were world class.

Taking on 2 undefeated fighters back to back in Snipes & Cooney was & still is a rarity for HWs. & from 1981-1985 he faced 6 undefeated fighters. 8 total if we include & novice 10-0 Frazier & a 14-0 David Bey.
No world class beaters, but he took on some young fighters who gave him a run, especially Tim Witherspoon.
Not any greats, but he beat some good ones. Frazier eye injuries played a part in not being on that resume & Ali, then Young took Foreman's confidence, so that would have been the only fight where a champ could've given him a run for it.
