Personally, I like Tucker. I would take him as high as early 6th round, maybe a very late 5th round pick. Personally, I wouldn't go much higher unless you are talking an elite shut down defender.
The big question with Tucker is how much offense can he provide? Is he the regular season guy or the guy in the playoffs, who when Svechnikov was out with a suspension, scored two big game winners against Mississauga?
If I were running a draft, to answer your question, yes I would draft him.
Now here is one for you Nugs: What do you do if Ryan Merkley is still on the board? I think on draft day he will continue to drop and we are just seeing the tip of the iceberg. Tremendously offensively gifted blueliner, but a train wreck in his own zone, takes foolish penalties, gives up on defense and looses his cool to often. What would you do?
