PPR or not, I'd go with Martin. He catches passes too.
I think PIT could get into a shootout with DEN, but PIT's o-line is horrendous and Dumervil/V. Miller are going to be teeing off on Big Ben. I could still see Brown snagging 8 / 110/ 1, but I like Martin for 100+ rushing, 30+ receiving, and maybe 2 TDs. Big projection, I know, but this is coming from a guy who grabbed Muscle Hamster at the top of the 3rd round.
