I decided to look up both players on mockdraftable.com, which has a nice visualization of the player’s combine drill stats compared to others of their same position group.
Here is Shane Ray. Here is Michael Sam.
It’s not even close. Sam is pretty close to the dead bottom in every category, and the only ones he surpasses Ray in (weight and arm length) he’s still in the bottom 40% of edge rushers as a whole. Ray isn’t great at everything, either, but he’s much faster in the 40 (89th percentile) and broad jump (79th percentile).
The article also seems to be mixing and matching numbers, since they said, for example, that Ray’s vertical of 33 inches was “only 3 inches higher than Sam’s” but Sam’s Combine vertical jump was 25.5 inches, not 30.
I admit I haven’t seen many Mizzou games but everything I’ve read, to me, makes me think that while they’re somewhat similar sized, Ray is much faster and can be an standing-up edge rusher while Sam is too slow to do so, and would need to play end with his hand on the ground, which has different requirements and he’s too small to do.
I’m sure that homophobia is alive and well in NFL locker rooms and many GMs probably see it as a reason to pass on him (since, by all indications, Sam is a fringe NFL prospect despite his college accolades). Comparing him to Shane Ray is not the way to prove that, though.
EDIT: Reading the comments, there are some other misleading omissions. Ray is significantly younger than Sam (21 instead of 24) which does make a huge difference in draft decisions. Also, when comparing their stats, the article just looks at totals, ignoring the fact that Sam played an additional year.
