Some captains take this VERY seriously!!
My first season on a new team and I found out I was going to be partnered with a woman who has an awesome game. I was excited to get to play with her and was hoping to pick up some of her court wisdom. She has been playing longer than I have been alive, and just has the most incredible court sense.
I mentioned to another friend that I was going to get to partner with Player A on the weekend. I never said which line we were playing or named any of the other players. Friend calls Player A and mentions that I told her we were going to be partners. Player A calls our captain and told her that I had blabbed who I was playing with. Then both Player A and the captain sent me very long, very explicit emails about what a dunce I had been for saying anything about the line up and that if I ever did it again, I was off the team.
I apologized profusely and played like utter crap during our match.
Well I dont think they shouldnt of called you a dunce, that's not really fair.
I think it would of been fair for them though to just specify how they feel about it so you know where they are coming from. (if they can do that without making you feel any worse or better about it)
In my case it was just a guy who admits that when someone asks him a question he cant lie. So rather than say what I would say, "you'll see when you get there", he instead told the guy he was playing.
But he's also a braggart and likes to talk trash to people so my fear is he's probably saying what line he's playing, etc..... Where as most of our team does not operate that way, we dont want to rile people up when they play us. (sort of like how in the pros they say not to make bulletin board material for the other team)
Im not interested in making him look bad or demeaning him, but Im just interested in not having the other team find out my lineup, so I guess I will just have to either not play him or not tell him until the very last minute that he's playing. (and have a sub available in case he decides not to play)
Ive played other teams where players (who dont care about the whole 'team' aspect but are just there to play tennis) have called me and given me their entire lineup, that's always nice.
But for the most part my team is not like that because most of us get along really well and we like it when the team does good. We dont have 8+ 4.0 players on our 3.5 team, but instead have a varying degree of talent so if we're playing someone who knows us pretty well and pays attention it's easy to create matchup problems if they know who's out there.
For example this guy is someone who in singles can beat everyone but 3 players on the team that we happened to play. If they know for sure he's playing #2 Singles then they likely wont make the mistake of putting anyone but those 3 guys there. Plus most of those guys hate playing him so they'll want to avoid that line. (he's like a mega-ultra pusher who can beat almost any real 3.5 singles player except for the ones who are almost 4.0 players)
I think for any team trying to take first or 2nd or 3rd even it is a big deal. Especially if you happen to be playing a team that pays attention (and not a "for fun" team which made it's lineup before the season started).
All the captain can really do is consider who the other team may put out there and try to make matchup issues for that match to give us a edge. If you know who's out there that makes a HUGE difference.
It was an extra big deal as well because it was a team that we have a pretty good rivalry with because it's full of friends, ex-teammates, and other notable players. We're not even scheduled to play this season but we're making up our own match between us before the real season starts (only with a 3S/4D format).
I could see where you are coming from though and some players may just not have thought about it and they let something slip. I dont have a problem with that, as long as they can respect our viewpoint on it in the future.
