I know a guy, former walk on played '89-92 after leading the state in receiving yards for a 2-7 team, who put a kid in the NFL after only coaching him his Frosh. year of HS at Hannahan, SC, no BS, just look up and go ask Chris Brown, Notre Dame & Dallas Cowboys....he will tell you about his former Husker volunteer coach and "the guy who had the biggest impact on his life" when he was awarded schools best athlete award his SR year. Note, back then during his HS days the next door suburb Goose Creek, SC was ranked in the top 5 in the US, we watched #1 GC beat Mt Pleasant (w/ a nationally ranked top 10 DE) 72-28 that fall.

but hell, guess now that I think about it, I put a kid in the NFL after only a couple years as his "OC" with the Little Mavs in South Omaha...... and mine's team made the Super Bowl his rookie year with the NY Giants & 8 seasons, LOL, can't forget about that guy, my "little fella's" dream was to be a RB he said.......so I let him-in a scrimmage game, I'm certain that his career rushing line still reads (2 carries, 1 yard, 1 fumble, 1 fumble recovery), obviously the biggest teaching moment in his football life, needless to say he made his & still makes money on the OL....right where I had him playing, 32 or so years ago? hmmm, maybe I should open an academy or something? oops, sorry C.B, great work.....coaching is so satisfying, you just got to love the ripple effect.
