Udyr's Model

Every time i play Udyr when ever i see him run Udyr seems very "blocky" and everyone knows that is fast, but it doesn't seem that way i know its because his model is outdated but still, when is running it looks like he is taking a stroll in the park but, spirit guard Udyr seems like he really is trying to chase down the enemy unlike classic Udyr. Is anyone else bother by this?
