Of the names you mention, none of Schultz, Vandevelde, Gordon, Manning or Del Zotto are taking up a roster spot from a prospect ready on the farm. That's not to say they're not garbage - but they're all on cheap, short-term contracts. And I get that a guy like Cole Bardeau, Scott Laughton or Taylor Leier could probably play now - but clearly Hextall feels they could do with more time in LHV. And all three have had major injuries which have slowed their development.
The Dale Weise signing does bother me because his contract, unlike the others, does stand in the way of young talent coming through. Hopefully its offset by either Read or Weise leaving in the expansion draft.
