These would have, could have, should have takes are wonderful. I can't say I liked the pick at the time, but unlike most I understand the reasoning and the potential in this kid. It doesn't matter what my GM abilities tell me about what the Dolphins should or shouldn't do.
If you scout by magazine or ESPN and that's your thing, Noah wasn't considered some 4th rounder. He was mostly in the late first/second round conversation based on physical abilities. This after playing the position for 10 years..oops..2 years. Flores and Alexander have both said his turning point and improvements are noted in practice and the Cinci game they specifically called him out.
To me, he has a chance to get there. He will also benefit from you know....practice..preseason...things they didn't get much of last year. Call him a bust if that's your thing...but his story is not written.
