Not every player on the team is going to be with us for ten years. Even if Henry only studs out for another three years, he's such a unique and incredible weapon; that's more than worth a late second round pick that is a 50/50 flip to be the next Christine Michael or D'Wayne Eskridge.
I'm not worried about the cap space. Every day I read news about X team restructuring contracts to clear up space with ease. Pretty sure we're allowed to do that too. And as for our other holes, we would still have plenty of draft capital to address those, and FA is tapped out anyway.
Also, it would make this team really, really fun to watch. That has tremendous value for me.
