His previous full lupine state allowed him to lift only 1 ton.  Sabreooth can lift at least 900 lbs.  He is also a skilled martial artist meaning that unless the Werewolf was as strong as Luke Cage's original strength classification of 3 tons (making him several times stronger than before) the writer and editor would have not had Sabretootj so easily handled.  However, despite this "king werewolf" thing, the name comes from an issue of Dr. Strange, he was much stronger than Sabretooth but still not able to over power Hyde who is 50 tons.  

Any fan of the character would know that this is inconsistant on Marvel's behalf and would note thast his strength enhancement is unspecified and ranges somewhere between Sabretooth (who was even stronger then than his 1st few appearances) a Hyde as per their battles.
