Lendl is still thinking in terms of the era he played in. Back then, the players did not really get along with each other. He and McEnroe couldn't stand each other for real. Connors and Mac did like each other, and so on. There was bickering and backstabbing back then. The #1 players usually stood off from the other players in the locker room...even Pete didn't 'hang' with other players. But in this era - things have changed. Generally the players (ATP players) like each other. They talk, hang out, joke around, practice with each other, etc. So I think Lendl is doing an injustice to Murray by having him act like they did back in his day. Just my thinking....
I missed those old days when they were really rivalries, the hawkeye was not there and the complains to the umpires.
somehow the atmosphere this decade seems like the 60's, (all friends), the difference is the money, public relations/campaigns and the coverage.
now, for example it is strange to see a player, a veteran like stepanek, showing the finger to his opponent, tipsarevic.
