"The biggest thing is health," Holland said. "If we can get to training camp (Sept. 19) and get [Pavel], [Henrik], [Darren] Helm, [Stephen] Weiss on the ice, we're optimistic we [have] the potential to be a decent hockey club."
Datsyuk and Zetterberg each missed 37 regular-season games last season. Datsyuk had a left-knee injury and offseason surgery was considered. Zetterberg had in-season surgery on a herniated disk that later caused problems with his foot.
"Last year we always had so many injuries that for the most part we were digging into our farm system," Holland told the website. "I'm hoping with the adversity we faced and with the quality minutes those young kids played it'll allow us to be a four-line team."
Helm played 42 games, limited by a groin injury and a concussion, and Weiss, who is recovering from a sports hernia, played in 26 (with four points) after signing a five-year contract as a free agent.
"[Stephen] said he's feeling great, he's training hard; he's played some (pick-up hockey)," Holland said. "So far all reports are he's healed and ready to roll in September."
