Smith played half a season in the league and gets already written off, give him time. The guy never had the benefit of learning from an all-time-top 5 defenseman and like someone mentioned had to play on the worst Wings edition since almost two and a half decade.
I hope he gets around 1,2 - 1,5 very managable cap hit and enough time to prove his worth.
I dont think anyone was "writing him off." A lot of us found ourselves yelling "dammit, Smith" more often than any other player this season. He simply made a consistent amount of poor choices when other options were available. The good news is that he will improve with experience, and I think a lot of us who are critical of his play hope that he does. I was expecting him to stumble a bit, just as I expect any rookie to struggle.
My general allowance is as follows:
1) Wingers: you get 2 full NHL seasons to show results (offensive numbers or defensive ability)
2) Centers: Tough job here. You get an additional season [3 total] to show results (faceoffs are scrutinized more and more each season)
3) Defense: Learning how to handle NHL forwards is formidable. I give 4 complete NHL seasons prior to ultimate critiquage. In Smith's case, he gets 3 more to show what he can do before I start calling for an inquiry.
4) Goalies: you have a screw loose. 5 seasons just because you control the least amount of the game, and may have a lackluster squad in front of you. Also- you are the craziest people on the roster and I usually cant figure you out.
