"I don't see why we can't make the playoffs," Walker told the Charlotte Observer after Thursday's practice. "I think we have a great team and are playing great basketball. As long as we keep it up, I think we can.
"We go out each night with the mindset we can make the playoffs. We practice like we can make the playoffs."
The Bobcats (22-28) have a two-game lead on the Detroit Pistons for the eighth and final playoff spot in the Eastern Conference.
Walker believes that's where the focus should be -- not on potentially adding another piece of the puzzle early in the NBA draft.
"That's ridiculous, as far as us tanking and getting a high draft pick," said Walker, who returned Tuesday after missing seven games with a sprained left ankle. "I don't think we need any more [high] draft picks at this point.
"I could never [tank]. I play this game to win, not to lose. If we are going to lose, we'll make sure it's not easy."
The Bobcats could potentially have as many as three first-round picks -- or as few as one -- on June 26.
The best scenario for the Bobcats is to make the playoffs, which would send their 2014 No. 1 pick to the Chicago Bulls, and for the Pistons' selection to be No. 9 or lower, so Charlotte would get it. The Bobcats also get the Portland Trail Blazers' first-round pick, which is likely to come late in the round.
