I would go after Rice over PT. He's been up against some tough defenses, and I'm very confident he turns it around. Both of these players have injury concerns, and you may actually want to stand pat. Charles has been great in limited work, and I'm convinced that he'll be a top guy at the end of the season, when it counts.
Are you winning games, or do you need to make a move now before falling behind in your league? If you're doing OK, I'd stand pat. If you need to do well NOW, well, I'm not sure either guy is the player you should be targeting. Rice is a bad call for this week, and the PT cruiser is on a bad wheel.
So... if you're looking for long-term value, I like Rice more of those two options. But Charles should be a strong option as well. If Thomas sees even a slight decline in carries, Charles' value will skyrocket.
