to guys like myself and delicreep , the nas pick was never baffling.
That 500k or so is the difference between us having Marty b on our team instead of Myers, but of course nassib instead of painter. I would venture to say that the drop off from painter to nassib is much smaller than Marty to Myers.
Personally I think Mcadoo will have a rough time of it. He was working with AR, who has the potential to be one of the greatest of all time. Also he needs to realize Eli is as slow as they come in the NFL(except Brady maybe). He will design plays where if they didn't work in GB, AR would scramble and make something happen with his feet/arm. Eli cannot do this, and Mcadoo won't be bailed out on bad play calls.
Plus the fact he has never called a play or designed an offense will come into play. I am not saying he cannot be a good OC, but there is going to be a learning period, where he find what works/doesn't work and what he needs to improve on. He will experience these "growing pains" with the Giants, and the team may suffer for it.
Hopefully he does a good job, but I think it will be very tough for him.
