There's been some talk on this forum about playing up in USTA leagues - some are for it, some are against it (personally, I'm against it) and it got me thinking; if you can play up then why shoudln't you be able to play down too? If you're a 4.0 then you can play on a 4.5 team - people on here say that it's good to play up to get experience against a player that is supposedly at a higher skill level. Using this logic, wouldn't you be able to play down a level too? Wouldn't these same players who want to play up all the time also want to play down so they can work on their weaknesses or try new tactics against a player that is supposedly a skill level lower than theirs? Or would the players that play up not want to waste their time playing below their level? I'm just curious - would all of you who play up a level in USTA leagues also play down a level if you could?
