I read where Mangiro lost 20 pounds off of his 2015 playing weight to improve his 40 time, weighing in at a svelte 302 pounds.

He then proceeded to run the 40 in 5.63. I wonder what he would have ran if he didn't lose the weight? Would he have been over 6 seconds? Just wondering, curious as to how a 20 pound weight loss for an olineman translates into 40 time improvement?
