Jimmy Johnson and Jerry Jones most definitely had their differences of opinion in their brief time together in Dallas.
The former teammates at Arkansas, of course, won two Super Bowls together as head coach/owner but then had their infamous breakup when the Cowboys were still in their prime in the 1990s.
They've seemed to make up, for the most part, and Jimmy offered his ol' buddy some advice on Twitter in regards to the NFL's biggest free agent, recently released quarterback Peyton Manning.
Manning is one of the greatest quarterbacks to ever suit up, without a doubt, but he's also 35 years old and has had numerous neck surgeries in the past year, and Johnson said Jerry should not even consider the older Manning brother over his current quarterback Tony Romo.
To be fair and to not perpetuate the idea around these parts that Jerry is basically an idiot of a general manager, he's also said as much, but Jimmy just wanted to make sure his old pal was still thinking straight.
"Stay with Romo," Johnson tweeted to a follower who asked who he'd take between Romo and Manning.
And for what it's worth, Johnson said he expects Manning to be with his other former team, the Miami Dolphins in 2012.
