having a debate with a friend and hoping you guys can weigh in with your opinion. my friend says at 4.0 level (and probably weaker 4.0 level), you can get away with fairly limited mobility, by playing a pusher game from slightly inside the baseline. i'm sure you know the type. 60 year old guys who flick back every ball... i concurred that these guys do very well in doubles (usually their preferred game), but that they'll get beaten in singles. i'm not talking someone who chases down lots of balls with pushing... but someone with limited mobility, few errors, good placement and hits most shots flat or with back/sidespin.... and i'm talking about reasonable 4.0 club tournament. not a regional where guys are sandbagging huge. thanks in advance for any responses!!
