OK, like any good Bama fan I've been studying the team roster and trying to memorize the depth chart before the season starts.  But I need some help.  What do the various names (Sam, Will, Mike and Jack) for the linebackers mean? And is this something universal in football or is it a Coach Saban thing? And are we as deep as we look at this position?

Thank you in advance for your help :) 

Ok ya'll, I'm a little worried.  I know it's not important where we're ranked, and I know the only important game is the next game, and I know it's all about the PROCESS, but I, for one, have really been enjoying this season, and I've really loved seeing this team I have worshipped since childhood at the top of the polls (which, by the way, has made me extremely unpopular here in Texas). 

That being said, I've been trolling the internet looking for answers to this question and coming up empty handed.  So I'm going to pose my question my fellow Bama fans:

Since we have a bye this week, if Texas Tech wins this weekend will they jump us in the polls?
