if they can deliver i don't care how much control they have.
kraft gave belichick control over football operations really soon after he got the job and he didn't have that great of a record prior to that.
i just don't see what the big deal in letting an HC have control over personnel, which is essentially all belichick has and what any other HC wanting control wants. who knows best what players a coach needs than the coach? let him get the players he wants and let someone else handle the cap stuff.
My biggest issue is that not that many of the "total control" guys are ever all that successful. The ones who do are the exception, not the rule. Heck, outside of Belichick, who can you name that's won a Super Bowl in forever?
All head coaches have control over who makes the final roster, who starts and who sits. Generally speaking, nobody has issue with that.
When it comes to control over who to draft, who ti sign in free agency, whose contract to extend, etc. That's where the issues start.
Veteran personnel guys generally hate when the coach inserts himself too much into the process. They want input from the coaches for sure, but they also complain that coaches have a tendency to "fall in love" with a guy's highlight tape and not look at the big picture.
Bottom Line: In today's NFL there's just too much to handle. That's why the total control model generally isn't effective anymore.
