Suprised by the fact that they recommend the majority of the time to have the top or second guy run the first leg which has the least potential to be the longest leg of the event and as mentioned requires a good turn runner.
If anything I would tend to put a better shorter sprinter, potentially a 55/60m specialist in this position due to their typical smaller size (potentially better around the turn) and good starting speed.
Overall, a very good article and a must read, espcially for new coaches not acquainted with the relay game.
