The similarities between the two QB's stem from Manziel's all or nothing approach to QB play that is eerily similar to that of Favre's.
At first, Favre was reluctant to be compared with any other player, that was until he saw the former Heisman Trophy play live.
Favre admits that he hasn't watch a lot of 'Johnny Football's' career, but he did reveal that he saw arguably Manziel's most defining and finest career performance.
Manziel threw for 346 yards and ran for 124 more (plus two TDs) during the game as he engineered a classic 41-38 comeback win for the Aggies October 12th last season.
Favre admits he was impressed.
"I haven't watched him much," Favre told USA TODAY Sports recently, "but one game I watched, for like three quarters, was the Ole Miss game."
"I almost thought I was watching film of a young Brett Favre," said the current Favre, who is 44 and spent 20 years in the NFL."
Favre revealed it was the win at all costs mentality that he saw in Manziel that impressed him the most.
"I didn't think I did a lot of things well (in college at Southern Miss), but he did. And and I liked the attitude of 'whatever it takes' — from that standpoint, I liked him."
