Also, Are there any other big names in the NFL that started in the AFL?

Yes Kurt Warner did play in the Arena Football League. He played of the Iowa Barnstormers and led them to the Arena Bowl in 1996 and 1997. They did not win the Arena Bowl. They lost to the Tampa Bay Storm and the Arizona Rattlers.

Here's an excerpt from Wikipedia. By the way, the Barnstormers moved to Long Island, NY:

After completing his college career at the University of Northern Iowa, he attended the Green Bay Packers training camp in 1994, but was released before the regular season began. Warner later worked at the Cedar Falls Hy-Vee grocery as a stocker before being signed by the Iowa Barnstormers of the Arena Football League in 1995. Warner was named to the AFL's All-Arena first team in both 1996 and 1997 as he led the Barnstormers to Arena Bowl appearances in both seasons.

In 1998 Warner took his chance and became a QB in the NFL Europa. During this season he played for the Amsterdam Admirals.
