Scared? They aren’t scared. The Charlotte Bobcats are pro athletes, so they won’t look at the demonic work of the NBA schedule maker and tremble. Their fans, however, are another matter. Never in their decade of existence have the Bobcats faced a taller order on the basketball court than this one. It is a quartet of doom, a four-pack of foreordained pain. The Bobcats will play the NBA’s four best teams by record in a row in a six-day span, from Friday through Wednesday. The first three games are on the road – a crooked path of torment through San Antonio on Friday, Oklahoma City on Sunday and Miami on Monday. That is followed by a home game against Indiana on Wednesday. So what’s realistic, Kemba Walker? Would a 2-2 split be a major victory when you are playing the first four 40-win teams of the 2013-14 NBA season consecutively? “We want to win all four,” Walker said bravely. “That’s the goal. It’s never ‘Let’s try to split.’ We want to go 4-0. That’s my goal, and I’m pretty sure that’s everyone else’s goal.” That sounds pretty ridiculous. But it is what Walker has to believe, and it is what a team leader should say. The Bobcats (27-30) do have a couple of “fours” on their side already as they attempt Walker’s 4-0 feat. They have won four games in a row entering this stretch – albeit against lesser competition. They also have had a rare four days straight of practice this week, from Monday through Thursday, which has given some relief to the veterans’ aching joints and a chance for new Bobcats guards Gary Neal and Luke Ridnour to get a crash course in the Bobcats’ system. “This is most definitely a challenge,” center Al Jefferson said. “And I am most definitely looking forward to it. We’ve won four in a row. I feel good about it.”
