Me and my friend were debating this ourselves. I personally believe that 4 wolves, whilst all smaller than one lion could take it down. I think this because even though a lion has far superior strength to a wolf in every way including bite force, I think that wolves outnumbering a lion 4:1 would give them the upper hand, their combined strength, intelligence and teamwork would in my opinion be able to take down a lone lion due to how wolves have evolved to become efficient group killers. Granted, this fight would probably never occur naturally, but it's interesting to think about.
For one, though wolves are pack hunters, lions are as well. However, wolves and lions do not typically reside in the same environments, so more than likely it would fight a mountain lion. For two, there are multiple factors to weigh in this question. How old is the lion, how old are the wolves, what is the size of the lion, what is the season, how do these animals behave? For the most part, mountain lions not only excel in strength, but in speed and agility as well. In many situations, wolf packs and far worse have failed to take down mountain lions. In one record, a pack of three pit bulls had encountered a mountain lion. The mountain lion mauled all three dogs, and walked away unscathed. The lion would be almost guaranteed victory.
The lion would be by itself, therefore at a massive disadvantage. This is a theoretical situation, nothing to do with mountain lions, you cannot simply change the debate topic. These factors are irrelevant when answering this question due to the fact that it should be automatically assumed that size is average for both animals, and both are fully grown. Season doesn't matter, it's a fight not a survival course. Three pitbulls? We're talking about wolves. Fully grown, wild wolves. Not little pitbulls that have no idea how to fight compared to a wolf. I disagree, we're talking four wolves. Not three pitbulls, versus one lion. The lion would have a hard time dealing with 4 wolves attacking it at the same time, the lion is simply outnumbered.
All of your statements were opinionated and none backed by facts. The topic was not changed, as the result was still one lion versus four wolves, regardless of the type of lion. There is no distinguishable average size, as all sizes are distinguished to their genetic coding. A full grown lion is a very vague term, as is a full grown wolf, due to the variety of species. The season does in fact matter, as certain animals, including many lions, are known to make more rash decisions in winter, whereas a wolf could use the season to its advantage. Pit bulls have shown physical superiority over wolves many times. Though the wolves do have a chance of winning, the odds are stacked in the lions favor.
