Top end challenge ...yes. Could be be #3 or 4 in state. Although in hindsight I would have to add "depending" on the field they play in.
If they play on normal HS fields it will be tighter, if they play on 120X70 ...no contest.
the other question... I know of some players one would wonder why they are not playing club. But in all the cases there were deficiencies for which pure athleticism cannot make-up for. If you cannot pass a ball accurately 10 yds or dribble under control, then no amount of speed can compensate. Sometimes people confuse speed with skill. Give me a thinking, skilled, quick player over raw speed anyday.
In many of the HS games I have seen, it would appear that speed is the main factor.
