I agree with you after seeing the video evidence,he is not a cap dump. I would be interested in seeing some video of how he deal with wingers with outside speed, as that looks like a potential red flag to me.
If he was available for a pick or some lower tier prospect i would be interested, but I really think Yakupov will turn the corner this season and we would regret trading him. If you look at his draft class, only Galchenyk has really put up any significant points and even that was only one season.
If you watch enough drafts and follow players you see that a draft year usually comes into main stream in their 5th year. Some players come in early, but they are usually the special players and hence the term NHL ready. 2012 is a below average draft and the players from that draft did not develop fast as a whole. There are some very good players in the group and a lot of talent, but none of them was dominant for the last 4 seasons. Yakupov is just another face in that group and while he was the first pick he did show some potential when used right. Why give up just before you really find out if he is a player or not. This years team has a whole different look and Yakupov fits the dynamic more now.
