Cash game action during a tourney--a thought

[bluechip270]

Most people say that the side games during a tournament are the best. However, I dont understand how this can be true. When there is a tourney going on, wont the cash games attract better players as a result? I would assume that this is even truer for tourneys with big buy ins.

What is everyones thought about this?

Also, my last two sessions at Commerce were during the day and I found the action much better than at night. Is this always the case or was that just an exception?
