I believe that the proper perspective is that McKenzie is a fine prospect coming back from injury. He is starting over after rehabbing for a year, and having been away from football for a year.
Perhaps some here can give me a list of defensive players who have becaome all-pros after coming into the league after a year of layover for an injury. I don't think that there are many,
So, while I certainly hope that McKenzie will be better for us that Crable and Wheatley, that remains to be seen. And yes, I am absolutely fine if he makes the roster as a backup ILB. He would be well worth the draft choice and the wait.
