C.Trent suggested moving the trade deadline back to August 15, giving teams two more weeks to evaluate their playoff chances. He's not the first to have this idea.
This year, I think it would help the Reds. They aren't playing well but are only 5 games out, and the Brewers, Cards and Pirates aren't looking real good right now either. In two weeks, the picture will be much clearer, and they would know more definitely if they should be buyers or sellers. Because it's so unclear now, they probably won't do anything.
