The difference between Schmaltz and Scherbak is that Scherbak has had his chance with two different organisations now.
He might be a late bloomer, but do you want to pick up a player who has shown nothing with 2 other teams and give him a chance before giving it to our own guys? A player who is probably 99% going to end up in the KHL next season?

2017-18 Tomas Tatar had 34 points in 82 games at age 27. 28 Points in 62 games with Detroit, 6 points in 20 games with Vegas. 2018-19 at age 28 has 31 points in 42 games.
William Karlsson 2014-2017 50 points in 183 games across 21-24 years of age with Columbus and Anaheim. 2017-18 with Vegas, 78 points in 82 games with 43 goals - nearly matching his career points in goals! 2018-19 with Vegas, 30 points in 45 games.

Pontus Aberg, 2017-18 played for Nashville and was claimed off waivers by Edmonton. 16 points in 53 games. Signed by Anaheim to a league minimum contract (650k) in 2018-19, 19 points in 37 games, T-1st in team goals, T-5th in team points.

Michael Grabner, June 2010 traded to the Panthers from the Canucks. Waived out of training camp by Florida, claimed by the Islanders - proceeds to put up 52 points in 76 games in the 2010-11 season.
***Rich Peverley, signed by Nashville as a free agent, put up 20 points in 73 games over 2007-09. Claimed off waivers by Atlanta Thrashers and puts up 35 points in 39 games. Only played for 1 team prior to break out after waivers claim.***
You never know who will have a fire lit under their ass by being waived, or not being re-signed and go on to have a respectable or very impactful season elsewhere when rejected, given away or being given up on by their team.
