I've blogged about Samuel Okuayinonu before.
The 6-3 270 pound JUCO DE visited UMass last weekend. His current 247Sports page has him leaning towards UMass.
Okuayinonu also has offers from Oregon and Maryland. Oregon has the best uniforms in FBS, but the Ducks already have one five-star and two three-star DE's in their 2019 recruiting class. I would think he would be in line for far greater playing time with the Minutemen. Okuayinonu would be an instant starter in Amherst.
