This.
I think many people quickly dismiss this idea of Blind because of his small stature but he has proven time and again that he is much more agile and intelligent to make up for his shortcomings.
Definitely a better option if we looking for someone to replace Carrick. More so than Schneidelin for me.
Last season even though he played in the CB position you would find him venturing forward, he wants to spray the ball, intercept passes before it gets to the back 4, wants to link up play. For me the way he plays is more suited as a DM and can definitely take the mantle from Carrick, whether that is for the next 10 years, I don't know and I don't think so, I think we may find someone that can do a better job, but for the foreseeable future, I don't mind to see him cement his place there.
I attached this vid just as a indication to that intelligent play and keen desire to venture forward, to play just behind the defense. You see in some of the cases his calmness in those situations is something that we need in a CDM.
