Thank u; why is this so hard to comprehend? Although I would argue Diaz is a good coordinator w/ his predecessors’ players.
Regardless, some guys in the industry are not meant to be #1’s, but they are good #2’s. Look at McDaniels for the Raiders; dude is dripping w/ accomplishments as an OC, but absolutely sucks as a HC. Norv Turner is another guy who comes to mind. There’s a slew of guys who r great DC/OC, fail as a HC & go right back to being a great DC/OC. Then some team will take another flyer on them, justifying that maybe they failed b/c of the previous team, & they find out the hard way, again.
Nothing to see here.
