you should probably make sure you know what you're talking about first. most would argue that donald brown hasn't really done anything yet either. in fact, goodson and brown have identical all-purpose yards this year, and goodson has done that behind 3 other RBs while brown has had significantly more chances to be the lead back. brown will get you carries between the 20s but javarris james is in line to get the goal-to-go carries because of his run style and his superior ball control. as such, brown's upside is severely limited.
though he is a 4th stringer, goodson doesn't have to worry about anyone stealing carries this week, and TB gives up 5.0 YPC and nearly 150 YPG to RBs. and ask any joseph addai owner; they'll tell you it's a nightmare when Indy falls behind early and just completely abandons the run. go with goodson.
