Side-by-side: Anderson Silva at light heavyweight vs 'The Spider' at middleweight

It's been a while -- years, actually -- since Anderson Silva ventured up from his usual home at middleweight to take on the seemingly bigger and badder light heavyweights of the Ultimate Fighting Championship (UFC).

Whether or not that's really the case is an argument for another day.

Instead, let's look at the other argument, that Silva will be giving up size and is a much different fighter at 205-pounds as opposed to 185.

As you can see in the above picture, which shows his weigh-in for UFC 153 today for his fight against Stephan Bonnar compared to his weigh-in for UFC 148 and his fight against Chael Sonnen, he looks a little fuller at light heavyweight but is there really that much of a difference?

Doesn't look like much to me.

By the time he climbs inside the cage, he says he'll be roughly 205-pounds. He also didn't cut much, if any, weight for this contest.

Anyone think any of this will matter come fight time?
