Agree with you on Kenneth Walker, I think he was a really good college back but he may struggle in the NFL due to his propensity to not just hit the hole & run.
Kennedy Brooks reminds me of David Montgomery, he probably won’t run a good 4.5 time, but he has very good contact balance & his field vision earns him extra yards by simply making the right move in traffic. When I watched him a lot at Oklahoma rarely did he ever hit the wrong hole or panic at the line of scrimmage like some RB’s do & immediately bail on the block developments, he got rewarded for being a patient runner often.
I’m interested to see how Breece Hall does, he kinda reminds me of a Melvin Gordon type, a big power back with more breakaway speed than most realize. He looks like a typical downhill lumbering runner, but he’s actually shifty with some quickness & good footwork in space. He’s like slow & fast at the same time lol. If he runs anything below a sub 4.6 I think he gets drafted in the 1st round.
Agree with your Isaiah Spiller assessment too, he’s not a straight line speed guy but is very agile & always makes the first defender miss, he won’t wow you with raw athleticism, but he’s a difficult runner to bring down in the open field.
Sincere McCormick is my big sleeper of this class, IMO he has potential to be a productive back in the league if he gets drafted to the right team. He has good burst & acceleration into the second level among this RB group IMO.
But agree with everything else you wrote, appreciate the insight brotha!
