That trade would not makes sense for Seattle in any way. Mack would represent a downgrade on Pocic, with even PFF having Pocic graded higher in both run AND pass blocking this year over Mack.....never mind Mack's $8M salary that you'd have to account for. No need to break what isn't broken. Similarly, Takk McKinley would not raise the bar relative to what Seattle has at the Leo position (the only position Takk can play) in the form of Mayowa, Damontre Moore and Alton Robinson. And allocating 4 spots to Leo's (never mind Darrell Taylor's potential addition later this season) is not good roster management. Besides, what Seattle needs is a viable INTERIOR pass rushing weapon (ex: Clinton McDonald circa 2013), not another replacement-level edge rusher.
