I thought Spann-Ford took a step backwards this year, but that's not all on him as the entired offense took a step back. He has intriguing size and can block, so I imagine the scouting community wants to get a closer look at him to get a better read as to how he might fit in a team's passing game.
I've seen mocks that have Nubin as a late-first round pick, but even if that's not the case, he'll be gone by the end of Day 2.
