bounce an idea off

[KLPNO]

Hello everyone,

From the book 99: Stories of the Game by Wayne Gretzky.

"[FONT=&quot]My brother Glen has been a constant at my side, always there to bounce an idea off of or provide another way to look at things—as have my brothers Brent and Keith.[/FONT]"

Does "[FONT=&quot]always there to bounce an idea off of[/FONT]" mean that Gretzky shared ideas with Glen, or Glen shared his ideas with Gretzky?

Thank you,

No, it means that Glen, Brent, and Keith were always there to offer an opinion on Gretsky's ideas. It does not mean that these people could bounce an idea off Gretsky, though it doesn't rule it out either.
You can also "throw out ideas" to people, and see what comes back. That means roughly the same thing.
