5 Spots I think Julio(or another FA WR) would be a great fit, and also have cap space at the moment:
1. Indy-Have a huge need opposite Pittman, and don't have a 1st round pick. I do wonder with the Rams signing Robinson, if they might prefer to go a bit younger with a guy like Beckham.
2. Chicago-With apologies to Byron Pringle, its Mooney and that's it right now. Julio would also likely be able to serve as a good veteran leader for a guy like Fields to lean on. I think this is the perfect landing spot.
3. Seattle-This would likely be somewhat contingent on trading DK Metcalf. If Seattle is looking to maximize picks, Julio could be a 1 year fill-in, who doesn't effect the comp pick formula. I could also see them going somebody younger though as they seem to be starting a full rebuild, maybe a guy like JuJu.
4. Dallas-With Cooper and Wilson gone, and Gallup re-signed but very iffy for week 1, Julio could serve as a starter and a valuable part of the 3 wide set. I do wonder if they would prefer a slot guy in order to have Lamb play a bigger role outside, in which case a reunion with Cole Beasley would make sense.
5. Washington-They've needed a guy opposite McLaurin his entire career. Ron Rivera is very familiar with how good Julio can be, and it would allow Curtis Samuel to stay in the slot, where he's most effective. Of course, they may also prefer Samuel's speed outside, and could target a slot guy like Landry instead.
I do think Julio is the highest upside WR left in FA, its just a matter of can he stay on the field, and how much will he want to get paid. I think he's got a good deal left in the tank.
