It seems inevitable, with nine days until the qualification deadline, that Team Scotland will have no men or women taking part in the 100 or 200 metres, nor the 4x100m relay.
Maguire, who will depart after Glasgow to take charge of sprinting at UK Athletics, said: "It's something the sport needs to address. I've been talking to people about it … And at our coaching weekends, and we've asked UK Athletics to delve into it more. It isn't acceptable we've no-one running 10.20 for 100m. It isn't acceptable we've no-one running 20.8 for 200. That's not even quick."
The Northern Irishman added: "Kathryn Christie has shown some promise but she's not ready. So I'm disappointed."
