Yeah it's a weird one. Like, I respect the film efforts. I think if you're looking purely at the film, Cole does some good work. It's the analysis (and existing biases) of that film where I tend to find myself having problems with the work.
I think Higgins has played well and he's taken advantage of the play time he's been given, but at the same time, how does it translate? It sounds weird to say for a rookie, but he's almost and is what he is guy at this stage. He's already pretty sound mentally, but the physical simply is not going to get better, and that's why I just don't see it with him.
He's not too different from Josh Ross (as a LBer) in my eyes. Of course, Ross made the team, but what has his career been? He started in almost the same boat - smart, instinctive leader from a bigger program that has athletic limitations. He's still kicking around the league but Ross has played exactly 0 defensive snaps in his career.
I think Higgins is going to play some games in his career, whether here or elsewhere. But the long term prospects are not great for a guy with his profile. I hope for his sake he bucks the trend, but there's a mountain of evidence that suggests otherwise.
