I think Porter has a chance to sneak into the 1st round, 2nd at worst.
If he had all the same measurables and career stats but played at a blue blood somewhere no one would bat an eye at him going mid to late 1st. There's been 3 DBs in the last 30 years with better athletic profiles and it's not like he wasn't productive too. Someone's going to see him as a moldable explosive project with limited wear and tear that they can polish up. Plus special teams ace that has shown he works hard, learns fast, and is a team first player.
I'm not saying he will, or even that he should, I just don't think we should be surprised at the possibility. This isn't the same ISU of 10 years ago. We have a strong reputation for producing reliable hard working professionals, and this year our guys have prototypical NFL size, speed, and quickness to go with it.
