May 7, 2021 With Mike Matheson hurt, the Penguins have used right-handed defenseman Mark Friedman on the left side in the pair with Cody Ceci. Friedman hasn’t been great. Today at practice, Chad Ruhwedel skated with Ceci. Ruhwedel is also right-handed. It’s worth a try, but doesn’t lessen the need for Matheson to return. Everything the Penguins do on defense is based on pairs that are lefty-righty. Lefties Juuso Riikola and P-O Joseph are available. Use one of them in Matheson’s absence. When the practice pairs were discussed on Twitter, several said that Ruhwedel never gets enough credit, or proper opportunity.
