For his body weight it's strong, but if you're talking best of the best he's not quite there yet. His bodyweight is right inbetween your typical 148 and 165 pound weight classes. I think as a 148er he would be pretty up there, but compared to the top 165ers he is not even close. Also not sure what he could do paused, which makes a huge difference IMO.
Most recently over the past 5-7 years or so there have been a surge of 165ers that have really taken it to the next level in raw benching. There has been half a dozen benching in the high 400s and a few breaking the 500 barrier. This doesn't even include the Paralympic or little people benchers that have done ridiculously crazy weight. There are many benching or have benched in the low to mid 400s raw near his bodyweight with a pause in competition.
Here is my friend benching 405x2 @ 165 with a pause.
He's done in the upper 400s raw in the past and is lifetime drug free. Keep in mind he is in his high 40s in this video with shot shoulders. I used to train with him from time to time back in 2005-2007 and he is a beast. If he didn't compete in a bench shirt for most of his career (multi-IPF world champ) I think he could have gotten close to 500 @ 165 raw.
I think he needs to get with the right guys and take his benching to the next level. Not to take away from this guys accomplishments though. He is definitely strong and has a lot of potential. Heck I couldn't even break the 405 raw barrier and I use to weigh 10 pounds heavier. I was damn close though....
Here are some of the best every 165 pound RAW benchers in the world (not including Paralympics or little people)
Rick Weil - 485 @ 165 (3-lift meet), 556 @ 181 (3-lift meet)
Joe Mazza - broke 500 raw
Stan Milostnoy - broke 500 raw
Joe Brewer - broke 500 raw
Daiki Kodama - 486 @ 158 raw (I think he's broke 500 raw in training)
I think if Maliek Derstine didn't keep going up in weight classes he could have possibly broke 500 raw @ 165 too. I think he's done like 525-535 @ 181 raw (3-lift meet). He recently bulked up and did 551 @ 197 raw in a 3-lift meet last month.
