seems like we've been lacking that super quick/fast RBs for a while now. i personally like the smaller- shifty shot out of a cannon type. derek brown, terry rodger, and cory ross comes to mind. these guys didn't need alot of room to run and the fact that they can reach top speed in a hurry helps too. i, for one, think that when it comes to short yardage situation , size is somewhat overrated. it's more about hitting holes and finding the crease to run through.... which brings up quentin castille. seems to me that he is somewhat the designated short yardage guy...always thought that helu would have been a better choice ( nothing against Q). he has a knack for finding a hole and he's decisive..for a big guy, castille seems to run better in space.....that being said, i'm kinda excited to see what marcus mendoza can bring to the table...like to hear some of your opinion
