Even if you are not a huge Dez fan.. you should be cheering for him ripping it up at the Saints and this why:
Jones loves Dez, if rumours are to be believed he was VERY disappointed that coaches pushed for Dez to be cut. So you could assume this was a decision taken by JJ reluctantly. IF Dez comes to Saints and lights it up then it gives Jerry just a little more ammo to convince himself that JG and co are not very good. It might also be enough to show why Dak is the problem and not the WR core. I have no doubt that Dez (through his ongoing friendship with the Jones) has made his thoughts on the playbook and Dak pretty clear.. seeing evidence of it on Sundays might just be the final straw.
If Dez comes out, gets 2-3 TD's, has 5-6 'splash' highlight plays and averages 40-50 receiving yards (all VERY achievable this season) then Jones is going to be pretty steaming imho.
