He doesn't consider himself a small running back who can't withstand the constant pounding.
Washington rushed for a career-high 164 yards on 21 carries in Saturday's win at Syracuse. It was the second straight game Washington rushed for more than 150 yards.
"I don't know where people... I can't understand that," Washington said and smiled.
"A lot of people say I am a small back. I am short but I am not small. I am over 200 pounds. I don't know where people get I am a small back. I carried the load before -- my freshman year I had 26 (carries) against Florida.
"I feel good. I feel healthy. I've been hitting the weight room throughout the season so my body feels good. I feel strong. I don't where people think I can't carry the load. I don't know where that comes from."
Washington, of course, has teamed with fellow tailback Lorenzo Booker to give the Seminoles a terrific one-two running punch.
FSU rushed for 258 yards against the Orange on Saturday, registering 13 of 23 first downs via the run.
The Seminoles currently rank 20th nationally in rushing offense at 200.2 yards per game. FSU hadn't registered more rushing yards than passing yards in three straight games since 1994.
Washington believes he and Booker have a good feel for each other, whereas last year the duo also shared snaps with Greg Jones.
Washington also credits the Seminoles' offensive line for FSU's running success.
"The rhythm is a lot better than it was last year, when we were rotating three backs and you might get in there every now and then. It's a lot better now," Washington said.
"And I think the main thing, me and Lorenzo have gotten very comfortable with the offensive line. We understand those guys. A lot of times, we let the offensive line creat the holes. Whereas last year, we would get in there and we were like, 'I wondering what these guys are going to to' because we really didn't have that much experience with them. But this year we are getting enough carries that we are getting used to our offense line and allow them to make the holes for us."
