You let the sieve that is Ellis walk, you trade McBain for a forward with some size, skill, and grit while he still has SOME value this offseason, and you draft Seth Jones with the #1 overall pick.
Upgrades the defense automatically, and letting Ellis go is addition by subtraction.
Wait, so you're saying that trading Ward and handing the starting job to Ellis at the beginning of the season would've been a BAD idea???
