I've always found his rivals offer list extremely suspect.
Look into his recruitment and you'll find excerpts like,
"Boykin entered 2015 without a single offer, but his stock has skyrocketed in recent months after tweaking his highlight tape."
...wha..?
And other than Boykin saying that Alabama, Ohio State, LSU, Texas and many other high profile programs offered him, you can't find confirmation from these schools of these offers.
As far as Clemson, he said in an interview that the Clemson recruiter was gonna offer him a offensive role, but Boykin refused. Do you still consider that an offer?
“He said they offered me to play offense and I’m not really interested,” Boykin said. “I pretty much told him that when I go to the next level I’m going to play defense. I don’t play any offense.”
From what I can tell, this is his legit offer list..

If his Rivals offer list was legit, he wouldn't have been a 3 star. He would have been a 9 star..
