A coach motivates much more than a captain does. Giroux will be fine, slow start due to injury and missing a lot of important pre season prep. When he finally starts scoring he will play much more relaxed. Frankly giroux is the least of our worries, we still have guys like Hartnell out there that are literally useless.
Depending on how things progress and what direction they want to take with this year, I'd seriously consider moving Coburn/Hartnell/Kimo/B.schenn
I think Coburn+Schenn could be close to land someone like Big Buff
If either hartsy or Kimo elect to be moved, good picks or solid young players could potentially be had for the right package
