Rhea would be a huge addition. He looks at data from performance metrics and helps tailor the S&C program based on analytics.
As I mentioned in other threads, there's wayyyyyy more to a strength and conditioning program then just slapping weight on a bar or having guys push sleds and run. That's very old school.
In the world of strength and conditioning, the goal is to get the most out of every athlete to help build muscle, maintain conditioning, keep things fluid, etc. Not all athletes are the same. Some need more, some need less in programming. Sometimes pushing too hard in programming can actually lead to on-field injury in certain cases.
Having real data to look at can help individualize a program to get the best out of each player while hopefully avoiding injury.
