Tupac and Notorious BIG will always be remembered for their feud, that most believe led to their murders.

It's easy to forget that the two Hip Hop legends were once very good friends.

The video of their freestyle over a Baby J beat was obviously filmed before their beef started.  I'm not sure of the exact year it was recorded, but it brings up so many possibilities had their lives not been taken.

Imagine if Pac and Biggie could have lived long enough to resolve their differences.  In a time when all the big names in Hip Hop are itching to collaborate with each other (Bad Meets Evil, Watch The Throne, Lil Wayne & Drake).  Just imagine a Tupac and Biggie album, and what it would sound like.

It's a shame that the freestyle is only 1:49, but it leaves the door open to question, "What If?"
