Strong went to Alabama's campus last week to meet with Saban.
Several other SEC teams reportedly courted Strong for coordinator or analyst roles, but he will instead become the latest former head coach snapped up by the Crimson Tide. The likes of Lane Kiffin, Mike Locksley, and Steve Sarkisian were once hired after losing their head coaching jobs. Sarkisian remains with the program as Alabama's offensive coordinator.
The 59-year-old spent three seasons at South Florida following stints with Texas and Louisville. He was fired in December after a disappointing 4-8 campaign.
Strong produced a 74-52 record and four bowl-game victories in 10 years as a full-time head coach. He had two 10-plus-win seasons at Lousiville (2012, 2013) and one at USF (2017).
