Why do people think Weal had real value?
He has 36 ES points in 124 NHL games, that 24 points for a full season, below average for a 3C.
He is undersized, has average speed though good quickness.
He is an below average defensive player. So a bad fit on an 4th line/energy line.
He turns 27 in April.
Advanced metrics love Weal, but those are predictive metrics, when the prediction doesn't come true, they have less value.
The hope was he'd produce up to his metrics, which should be a 30-35 ES point 3C. That never materialized.
At some point you realize that he's good at possession, but not closing the deal, and at his age, that's unlikely to change.
We got a 5th rd pick for a full season of Cousins at age 24 (but through in Madsen).
So a 6th for half a season of Weal seems reasonable.
