The term "stretch-four" to describe a power forward with deep shooting ability has come in vogue in recent seasons. The Pistons will be missing their version of a "stretch-four" when they open the season tonight at Indiana. Charlie Villanueva is missing the first three games of the season because of a suspension resulting from an altercation with Cleveland's Ryan Hollins in last season's home finale. So expect a healthy dose of Jonas Jerebko, Jason Maxiell and Ben Wallace. None of them really qualify as a "stretch-four," although Jerebko does have three-point range. Pistons coach Lawrence Frank didn't rule out using small forwards Austin Daye and Tayshaun Prince in that role if matchups dictate it -- although he said the team really hasn't had time to work on it in practice. He said he would prefer to keep them where they are, but who knows how things will unfold? "It could be matchup-based, it could be performance-based, defense-based," Frank said Saturday at the team's final practice before Christmas. "Also it could be based on second unit, what parts fit better than others. All those things come into play in terms of having a good balance on both units."
