Baldy thinks Cesar Ruiz’s best position is Center

Leave no stone unturned. No man is bigger than the individual unit, putting guys where they can best make the most impact is more important than keeping guys where they've been.
As Payton used to say it's not about having the best players, it's about having the right players that perform the best together.

Even if Ruiz would be better at center than he is at guard, that's not enough of a reason to move him to guard.

The way a coach has to look at it is which gives me the best OL:
Kubiak will do what he thinks is the best combination. He's not going to move Ruiz to C, unless that makes for the best OL on the field, not on paper.
