The Penguins' developmental pipeline is all but clogged with promising young defensemen and a few have generated some pretty gaudy stats.

Derrick Pouliot a first-round draft choice in 2012 piled up 45 points in 44 games last season with Portland in the Western Hockey League.

Olli Maatta selected shortly after Pouliot accumulated eight goals and 30 assists in 57 games with London of the Ontario Hockey League.

Those two are among the headliners for the Penguins in a prospects tournament which continued with a 4-3 shootout loss to Toronto Saturday night at Budweiser Gardens.

Harrison Ruopp acquired from Phoenix in the 2012 draft-day trade that sent Zbynek Michalek to the Coyotes put up some offensive numbers in his four seasons with Prince Albert in the Western Hockey League too.

Just not many.

To be precise three goals and 31 assists in 214 career games.

While averaging a point every six games or so isn't a terribly effective way of getting noticed by scouts there are others.

And Ruopp found a pretty good one.

He hits. Hard. And often.

And if he continues to do that as his career progresses -- Ruopp will play pro hockey for the first time this winter -- there's a pretty good chance he'll show up on the Penguins' blue line someday.
