While I think that the panic regarding Guhle playing on his offside is ridiculous, it doesn't prevent me from liking the idea of trading one veteran LHD (Matheson) for another quality veteran RHD instead.
A legitimate 1st pairing, shutdown RHD to play with Guhle is definitely not a bad idea, but we'd still be at least a year two from icing what such a pipe dream (quoting other poster) might allow once a few prospects mature some:
Guhle - Parayko
Hutson - Reinbacher
Xhekaj/Engstrom - Mailloux
6 years of Parayko at 6.5M would be great (ages 31 through 36).
Would St-Louis really take Matheson for Parayko? If not, what would the plus need to be?
I'd offer Matheson + Barron.Both would improve the Blues D-Corps, overall, IMO, even when losing Parayko.
