Prove he did when Strange clearly cut him off from the Odin Force with that amulet. Otherwise it's baseless speculation. He can't "absorb" more Odin Force, either. He already had the totality of the OF at that time; just not the wisdom to use it like Odin himself.
Which means, for all intents and purposes, Thor couldn't use the Odin Force consciously. Which means Thor without the Odin Force = Classic Thor in terms of physical ability.
Nothing was stated that the OF that was inside of him already was drained from him by Strange. He still had the OF in him, Strange just stopped him from continuously tapping into that power.
Strange : "The Odinpower is no longer yours."
Thor : "Impossible !No mere mortal can do this."
Strange : "No . But the Council Elite of the Pantheons of Earth can."
And if he can't tap into the Odin Force, it doesn't do shit for him.
It was clear, abundantly so, that Strange stripped him of the Odin Force thanks to the Pantheons of Earth's gods help. Thor, without Mjolnir or the Odin Force, beat and killed Hulk and Thing after hours of grueling combat and not without injuries.
Is this a joke? The Savage Hulk would destroy Ulik hand-to-hand, whether he's "at his best" or not. It would be close for awhile until the Hulk gets mad and 'smashes'.
As for the second scenario, how on Earth can Ulik come close to beating the Hulk if both are going all-out? This fight wouldn't last a page.
Against a Professor Hulk who would turn back into Banner when he got angry. Thor didn't win the fight anyway although he looked to have an advantage in the end.
