I personally feel in todays game you can get away with a weak secondary as long as you can rush the passer, your pass rushers can always make you CB's look good if the QB has little time to process info and make accurate throws. On the other hand you can have a great secondary with weak pass rushing and if you give a quality QB time to throw he'll find open WR's making the secondary look bad. That's just my opinion though I'm sure many will disagree.
As far as Cook, Mckenzie is smart taking him.Stock piling QB's you can develop lead to higher draft picks later down the line. I just don't see any chance cook has to even compete for 1st string, more of lets develop him hopefully he has a few good preseason/meaninglees game and some team falls in love with him and we can trade him for a second round pick. Belichek has done it in the past and I believe Mckenzie did too already when in GB with matt Flynn, but I'm not 100% on that.
