Do u know why Alabama and TN Vols are big rivals?

There has always been an intense rivalry between the two. The first games they played back in the early 1900's were so unruly that they were suspended until 1928. The Vols won that game and Neyland, at the time, famously said, " I know we won, but what was the score?" If you ask me, that pretty much set the rivalry in stone. More recently, in 2001, a Bama booster was accused of bribing a Memphis high school coach to convince a player to attend Alabama. A "secret witness" in the case was later proven to be Phillip Fulmer. That is why I personally hate them.

Anybody can copy and paste wiki I suppose.

Despite the heated in-state rivalry with Auburn, Bear Bryant was more adamant about defeating his rivals to the north, the Tennessee Volunteers.[115] The series is named the Third Saturday in October, the traditional calendar date on which the game was played. Despite the name, the game has only been played on the third Saturday five times between 1995–2007. The first game between the two sides was played in 1901 in Birmingham, ending in a 6–6 tie. From 1902 to 1913, Alabama dominated the series, only losing once, and never allowing a touchdown by the Volunteers. Beginning in 1928, the rivalry was first played on its traditional date and began to be a challenge for the Tide as Robert Neyland began challenging Alabama for their perennial spot on top of the conference standings.[116] In the 1950s, Jim Goostree, the head trainer for Alabama, began another tradition as he began handing out cigars following a victory over the Volunteers.[117]

Between 1971–1981, Alabama held an eleven-game winning streak over the Volunteers and, between 1986–1994, a nine-game unbeaten streak. However, following Alabama's streak, Tennessee responded with a seven-game winning streak from 1995–2001. Alabama has won the last five meetings from 2007–2011. Alabama won the most recent meeting 37–6 in Tuscaloosa, and leads the series 48–38–7.[11

it dates back to 1902 and neyland started threatening alabama for the best team in the sec.

mainly because they are border states and some are bigger than others
