I think you have a great opinion on your team and you sure know your stuff. I don't think Cousins would be a good fit in your offensive of scheme. He obviously has more of a long ball then your current QBs. I think Tyrod Taylor would be a great fit, a better version of Geno Smith. He can throw, run, and make plays. He would need some support from your OL. I think drafting another QB means another year of rebuilding. But as you mentioned some of the QBs in this years draft can be solid starters.
Good luck and GO Jets Go!!! LOL
