I might be in the minority here but I think Jeffries looks pretty good here. Good left hook, fast hands (especially for such a big dude). He's obviously not technical master, he struggles to cut off the ring and his footwork is subpar. However, he's still better than a good chunk of the current top 20. Overall, Jeff seems like one of the better filmed heavyweights from the era. I saw someone compare him to Chuvalo, and I think it's a pretty good comparison
