Pinto has played RW, he played RW at the WJC where he quickly became one of the best players on the US sqaud as well as the entire tournament playing against his peers. So it's not like he has never played the position or played it badly, he played it & he was great at RW in that tournament. He's also as a rookie won the 2nd line centre position twice, he quickly moved up the lineup at the end of last yr when he first arrived & won it straight out of training camp this yr beating out all other contenders. I don't see why they both can't play on the 2nd line & share the centre position when & where required.
Stutzle is not great at faceoffs, everytime they lose a faceoff they lose possession & the puck potentially for long stretches. Tkachuk is taking faceoffs for him now, why couldn't Pinto do that he's very good at it? Why couldn't Pinto match up against some big centres like Mathews when there is a difficult centre matchup for Stutzle? There is no good reason why both can't play on that 2nd line, especially when they still have White around. Giroux is the other option at RW that could help Stutzle with faceoffs but until he becomes a member of this team is just a pipe dream.
It's stupid not to consider that Stutzle still has some weaknesses & may still have some difficult matchups in the NHL & they should use every resource to minimize those inbalances. It's a strategic game & all it takes is one lost faceoff or one bad matchup between losing a game & winning a game. Stutzle is trending towards being a great player, but so was Pinto before his injury. Stutzle is dynamic & flashy while Pinto is solid, reliable, consistent & dependable & Ottawa needs both IMO.
