Just try 
Top lane, the only champion who can get 13% life steel and enough burst at lvl 1 without any life steal runes.
Edit: dont know why people say GG even in forums.
GG = GOOD GAME for those who don't know
Down vote me Juggernaut mains :D
CPU BIanc2 votesa champion with a weak laning phase and who can get kited super easily and is absolutely useless late game? Im sure that'll teach darius a lesson.
Idroold2 votesNo offence but udyr do not have a weak laning phase, but that depends on the player how he is playing. U can literally make ur opponent stop farming. he is not so waste in late game as well.
Flying Bok Choy1 votesWat. Those aren't sentences. If English isn't your first language that's cool and all, but at this point google translate might be the better option.
But as for what I assume you're saying. Try playing against literally anyone with damage or tank stats. They'll take that hit, and heal off flask or get armor 5. Or they'll out trade you because they have better dueling skills, such as Fiora. Other champs like gnar/rumble who can kite you will just decimate you.
Idroold1 votesthis post is against Juggernauts, not against fiora or gnar and no one will place a ", " before AND.
Flying Bok Choy2 votesLike I said though. they can get armor 5 or flask, and out sustain you as udyr has mana problem.
Idroold1 votesStill he can beat out them
Flying Bok Choy2 votesAt this point, it's just a "my dad's better" competition. You're never going to agree. So whatever. GG
Sulghunter1 votesJust try to kite Udyr. I dare you.
Seriously, that crap is un-freaking-kitable. And this is coming from someone who mains Ashe and Quinn. I doubt even Kalista can kite Udyr.
Flying Bok Choy1 votesLate Game? No. Early? Absolutely. Especially in a lane with a tower, where one dash/jump/burrow/blink/etc. gets you to the tower.
TyroneWatermelon2 votesThe only juggernaut I have a problem can is gayren. Anyway it depends on how you play udyr,if you can button mash,right click and know when to disengage you have a chance.
Idroold1 votes+1 for the summoner name :P
Flying Bok Choy1 votes:/ Because 10% at lvl 1 is 20%. W give s 10/12/14/16/18. Compared to Darius who has 12% missing health. Considering the missing health will be greater than the damage dealt. Darius' heal is way better. Considering we seem to be basing top laners based on how much they heal themselves 
op.
Idroold1 votesoh yea true but he can get 13 % and that is alot, and darius can heal only when he hits enemy, and udyr is melee, i dont think he will ever hit udyr with his Q................... MANA problems :( and u can able to stop them farming
