September will pose challenge for Collins

With so many rookies on the team already, Collins isn't eager about bringing in reinforcements. "There's a fine line [with] September call-ups," he said. "The position some of these players are in -- they're fighting, they're trying to prove they belong. Do you sit those guys in September? I don't know if it's fair.

"They've been beating themselves to death all summer long, going through the good times, the bad times, all the turmoil and all the ups and downs."
