You are certainly entitled to your opinion and I totally respect it. But the facts are not what you may think they are. The kids you are speaking of learned toughness from many other things. Reed didn't show up one day and Jake Sturgill was a 2 time all state QB. Matthew Fulton wasn't beast of a running back. Derrick Yates didn't just become a college prospect because he showed up and the list could go on.
The current list of players who are seniors and started out in Reed's system didn't become tough and hard nosed because of his system. That trait came from playing together since they were 6 years old in flag football. That trait came from them becoming a band of brothers all the way through their youth league days, middle school, and JV. There were many other factors involved than saying "he toughened them up".
Consider this:
2014 8-2 Colobro/ Amburgey on staff the year Reed is named head coach
2015 9-1 Colobro/ Amburgey on staff
2016 9-1 Colobro/ Amburgey on staff
2017 6-4 Colobro/ Amburgey NOT on staff
2018 8-2 Amburgey named head coach
On a footnote: "Give them a couple years...they be back to being soft again" This sounds like wishful thinking.
