Bret Bielema wants to hire M's S&C coach Ben Herbert

the best S & C guys are so wired that, without the aid of caffeine or other substances, they will vibrate even when seated or standing still.  kind of like a bird dog where some breeds are simply way more highly strung than others.   

I think that's true of some for sure.  It's probably also because some of the more well known guys like Scott Cochran embody that.  I also think guys that tend to gravitate towards football also tend to be more this way.  Football S&C coaches in general tend to be louder than say basketball or baseball S&C guys, particularly at P5 schools where football & basketball have their own S&C departments and then the other department does pretty much every other sport.  These guys specialize in football and often football position coaches are also loud.  It's a part of the football culture.  But, I don't think it's a requirement to be a good coach.  You have to have energy.  No one wants to be up at 6am to train.  And, lots of players would prefer to play than train, so a good coach motivates and energizes their players.  But there are lots of great S&C coaches that are not loud or overtly energetic.  They can deliver their message in other ways.

Beilein could do his fair share of yelling. He just wasn't a one trick pony about it. 

We rarely had a push off the line of scrimmage on offense and could never get a half yard on fourth down. We really need an upgrade in strength this off season

I'm highly skeptical a new S&C coach can make a significant impact on this.  This is more about their age and experience level and level of development IMO.  When guys are young, even if they are big and strong, they have difficulty playing fast and hard because they are always thinking about their assignments.  Once they know what to do, then they can focus on doing it hard and aggressively.  They are just still learning.

It will help if the team is able to use the weight room this offseason.  That wasn't the case for much of the last one.

My memory ain't foggy...  the people promoted Barwis to no end and indirectly implied that Gittleson was chopped liver...  seemed very wrong to burn a guy who had great success here.... same was done with deBord by Brian.

The former (what Michigan did Bo thru Carr) is appropriate for body-builders but tends to make people slow and weaker than they should be WRT muscle cross section size. 

Now, show me some research that indicates this might actually make a noticeable difference in the push of our offensive line.  You won't because it doesn't exist.  Yes, we know that different types of training produce different adaptations...SAID principle (Specific Adaptations to Imposed Demands).  This is exercise science 101.  Every strength coach knows the difference between compound lifts (heavy multi joint lifts), power exercises (Oly lifts & plyos), accessory lifts (single joint exercises), stabilization exercises, flexibility exercises, etc.  Every strength coach also knows in order to maximize performance they need to use a blend of all of them and they need to suit it to the individuals needs based on a combination of training experience, strengths, weaknesses, and adaptability.  Some guys may lean more towards one philosophy than the other ie focusing on compound ground based lifts to maximize strength, focusing on power exercises to focus on rate of force production and explosive ability, focusing on mobility and stability work to keep the athletes healthy and prevent injuries etc., but they all do some level of all of them.  I don't personally believe that the science is at a level where we can definitively say that one focus (while still using all of them) is any better than another at something as specific as improving push on the offensive line, or even if it did improve that it wouldn't be to the detriment to another area such as agility in pass pro.  Anyways, that's a long way of saying I don't think the philosophy of the coach or their training style is as important as their ability to motivate their players and their organizational skills.  You need a baseline level of knowledge, after that it's more about the person.

Possibly, but there's so much going on from the land-of-make-believe read-option that allows opposing D's to sell out to stop the run once they realize the QB isn't going to keep, to over-complication that makes players think to much and appear slower /less aggressive than they really are as well as several recruiting busts that make our preferred press-man schemes unworkable, not to mention the drive/momentum killing gimmick & wildcat plays. I'm not sure we can say the S&C guy isn't motivating the team with any level of certainty. 

 Our guys just don't seem as jacked and angry as other teams. 

Probably more about the players we're recruiting.  It's been a criticism of UM's recruiting that we tend to focus on the more middle to upper middle class good kids with good educational backgrounds rather than the tough inner city kids.  That's probably a drastic oversimplification, but I do think there's some truth that we don't recruit as tough as kids as we used to and kids today are also a little softer as a whole than they were 20 years ago.  If a top 100 kid isn't play by his sophomore year, get's benched, has injury difficulty, or gets in his opinion too much constructive criticism, he's in the portal more often than not.

I saw that guy tying a woman to the train tracks many years ago.
