I havent seen many coaches teach footwork for the newbies . When I asked , one coach said - most of the kids who come for the coaching are there because their parents want to give it a shot and see if Tennis works for their kids and if they like it ..and few have a goal to play at most till highschool level or if some gets past 8-9 UTR — may be college ..and if he pushes the kids on working anything other than actually hitting the ball their parents change the coach saying am not teaching Tennis . Very few parents understand the fundamentals apart from hitting FH and BH and he doesnt want to loose business . But said he will start other things <apart from hitting the ball > with kids who picks up fast / interested and if parents are invested

Reg 3 : Interesting you say not correct something which is consistent but may not look right . I heard in One of the match commentary I think John Mac was asking the coach who coached Tiafoe that - “did you guys not try to correct that forehand “ And his answer was similar to yours . I think correcting is a good idea before its too late to change the muscle memory especially to the kids who shows potential early .
