Zeke, Cook, Fournette, Hunt are all guys that I think could help the team, but shouldn't be treated like priority free agents for this Patriots team. Now that the Hopkins ship has sailed, unless a high quality OT suddenly comes available (very unlikely), they're better off using the cap space to extend some players and reduce future hits so they can strike at the next opportunity.
Now, if we get a week or two into training camp, and one of those guys still isn't signed and suddenly would come in on a 1 year, short money prove it deal, I'm all for it. Especially because, by that point in TC, they should have a good idea whether Strong or Harris are poised to take a second year leap or not. And while wide receivers may not view the Patriots as a place to rehabilitate their value, New England is definitely still a place where running backs are featured, so the incentive might be there for them.
