Trengove is weighing up free-agency offers to return to his native Victoria after being dropped from Port’s team for the last month of the season.
“He has got to make a decision … it’s up in the air,” Boak told reporters on Wednesday.
“This is footy now. Free agency comes around and he has got to look at what is best for him and his family.
“We respect that; we understand that. We as a club love Jacko and Jacko absolutely loves the club but he has got to do what is best for him.”
The Western Bulldogs are believed to be pitching for Trengove, a versatile 153-gamer, while the Power are understood to be keen on Brisbane midfielder Tom Rockliff.
“I don’t even know if we have spoken to him but he’s a quality player … it elevates your midfield if you bring someone like that in,” Boak said of the Lions’ ex-captain.
Boak said he and his teammates were still grappling with their crushing extra-time elimination final loss to West Coast.
Eagle Luke Shuey kicked a goal after the extra-time siren in a result still raw at Port.
“There is no doubt there’s going to be a lot of hurt from that and a lot of burn that will drive a few players,” Boak said.
“It’s probably the worst result and worst loss I have ever been involved in, in a final like that where we controlled the game for a lot of it and wasted opportunities.
“And to go down in extra time, after the siren, is pretty hard to cop.”
The Power skipper downplayed president David Koch’s post-game remarks that players were to blame for not following coach Ken Hinkley’s game plan.
“We (players) have spoken about it,” Boak said.
“We have got to talk about it. We know that we’re all on the same page and all looking for the same outcome.
“He (Koch) is really passionate about the club …there is no doubt every player at out club cares about winning a premiership and that is all they want, and he knows that.”
