Matthew Golden Speed Rating

Can someone at EA please share the logic behind Matthew Golden’s speed rating? 

Him & Maxwell Hairston ran the same 40time, yet Golden is a 91speed while Hairston is a 96speed..?

Even if you take away that comparison, he should still be at least a 94, 95spd. A 4.29 does not equate 91!!?? He’s the fastest packer receiver yet has the lowest rating. 

The logic is confusing for multiple reasons. Surely someone at EA understands the frustration and can get back to us. Thanks. 
 
Please do not use “game speed” as a deterrent for Golden. I live in Lex KY- where Hairston went to school. If game speed was the logic, he wouldn’t be a 96.
