I would say in most cases the very fact that you're trying to do both very often leads GMs to make questionable decisions at draft table, trades, and July 1st. Not impossible just extremely difficult.
Totally agreed and Chicago and Kings are prime examples
Big cap busting contracts all retained with declining assets and too late for the draft to save them
Seebrook, Keith , Quick etc....should of been peddled for youth
That's why I respect what the Rangers have done , starting unloading 2 years ago ( window was over ) and replenishing with picks , prospects and a ton of cap space available in 1-2 years . Kreider and others will be unloaded this deadline as well .
They need way more help but at least they are building some functionality and have some players to work with down the road
