Mic'd-up Joe Thornton's youthful energy on display at Sharks practice

Whether or not Joe Thornton is a national treasure is debatable, but he's certainly a regional one.

The future Hall of Famer was mic'd up at a recent Sharks' practice, and he put that quality on display. The 40-year-old didn't appear as if his age has caught up to him, as he was quite talkative and involved throughout.

Just watch for yourself:

Whether it was chasing on the forecheck or missing an empty net, the eldest member of the Sharks looked anything but. Enjoying his first healthy offseason in recent memory, Thornton's energy is certainly palpable, and that bodes well for the Sharks as they attempt to get back to the playoffs for the 20th time in the last 22 seasons.

Thornton signed a one-year contract at the beginning of the month to return to the Sharks for his 15th season in San Jose. He'll be one of four alternate captains on the team, after Logan Couture was named the 10th full-time captain in franchise history, taking over for the departed Joe Pavelski.

With Pavelski, Joonas Donskoi and Gustav Nyquist leaving in free agency during the offseason, the Sharks are counting on several prospects to take a step forward this coming season -- and on Thornton to help them succeed at the NHL level. While line pairings are still in flux, it wouldn't be shocking whatsoever to see Thornton paired with one of those prospects on his wing.

Based on Thornton's mic'd up session, he'll be talking that prospects' ear off all game long.
