I told him I would not say but did remind him who the son was up against and basically told him to take the job or take his chances. If he had a 0.00% chance of making one of our two teams I would have told him so.
I've had parents present that situation to me in the past. I never say they are going to make our team, but I have told some parents it might be wise to take the other spot. That's the extent of my possible answers. If they are stuck in the middle I remind them that I am not going to make a decision for them.
It's a problem when every team is running tryouts over different time frames. I could easily say this type of parental dilemma is not my problem, but that's not a statement I am comfortable with. But I have to protect our process and be fair to the group in tryouts.
I hope parents have a "plan b" in their pocket when they are attending multiple tryouts.
This goes hand-in-hand with my lack of comfort in recruiting when it comes to youth soccer.
