In Wood, the Sharks add a promising, all-around defenseman--albeit an inconsistent one. He will initially serve as organizational depth, but Wood has a chance to play a regular shift in San Jose at some point.

Helewka is a decent winger prospect with pretty good size and playmaking ability. He turns 23 next month, so a change of scenery should help him. He will likely spend most of 2017-18 in the minor leagues.

Neither Wood nor Helewka are recommendable as fantasy assets for 2018-19. Instead, fantasy leaguers should take a wait-and-see approach with both prospects.
