“As a 6-foot-5 receiver who ran a 4.30 40-yard dash at the combine, Thornton drew comparisons to Calvin Johnson and DK Metcalf,” Michael Florio of NFL Media, not Pro Football Talk, wrote. “Aggressive comps for a fourth-round pick, no doubt, but the truth is that few human beings are this big and this fast. The Raiders are searching for a viable receiver to complement veteran Jakobi Meyers. Thornton’s ability to stretch the field should make life easier underneath for Las Vegas — creating plenty of space for dynamic tight end Brock Bowers — so do not be surprised if he sees regular playing time. Thornton likely will be a bit of a boom-or-bust, but he certainly brings upside.“
