I drilled into your article link. Here is the actual quote from Lurie:
LeSean McCoy is a great running back - all time franchise leader," Lurie said, via NJ.com."Great guy in every way. (But to) maximize his power spread offense, (Kelly has) always admired the one-cut runners."
There is no direct quote anywhere from Kelly about a mismatch in running style vs scheme . So in effect , Peter King is reading a bit into Lurie’s statement when he tweets that he heard that McCoy is too much east-west. Interestingly there is also no mention about McCoy refusing to hit the hole immediately and take those “abundant yards’” you speak of . Incidentally, what was the running output when Philly plugged in those new one cut runners? Was there output abundant?
