I respectfully disagree about your McCord assessment and provide 2 reasons as to why:
1) Mccord rarely had enough time to sit in the pocket at Syracuse and go through progressions. The Syracuse O-line wasn't good enough to give him that kind of time. When McCord had success, he had to make pre-snap reads or create one on one match ups for his receivers by moving the safety. 2) He threw for 4,750 yards and 34 TDs (most in NCAA) at Syracuse, with Syracuse level talent in the ACC. 65% accuracy. His #1 RB rushed for over 1000 yards, so there was some offensive balance. So, I'll answer your statement with a question. How does McCord throw for that many yards and TDs if he processes slowly? And we all know it wasn't with his mobility. The answer is pre-snap and quick processing skills.
