Baresi was better than Maldini at CB.
His peak was untouchable. The man suffered a serious knee injury in the first WC game, that requires four months rest, and came back for the final and put in the single greatest individual defensive performance in history, in his 30s no less!
I get the Maldini stuff, but it's so overblown with him because he started playing at CB due to his age, and there's no way that CB Maldini was better than Rio, Nesta, or Cannavaro. Now peak Maldini at full back? Then yes, probably the greatest full back in history.
Both Baresi and Maldini were amazing defenders among the best in football history. They were legends off and on the pitch, their quality was undisputed and at their best (particularly Baresi) they played among the best players in the world. They also seem born for the role they played in which helped them a lot, particularly Baresi (which I explain later).
However if one has to nitpick by putting them both under the microscope then you'll see slight differences. For example Baresi was 5ft9 ie the same size of Lisandro Martinez. Don't take me wrong, Franco was a clear upgrade in almost everything on Martinez (though passing wise Lisandro is slightly better) but there's a limit to the muscle and the amount of aerial duels a 5ft9 CB could do. That didn't bother Baresi up until the very end and the reason were various. First of all the Serie A of the time hardly had giants. Signori, Vialli, Mancini, Baggio, Schillaci, Maradona and co were shorter then 6ft tall. The few who were taller then 6ft (ex Batistuta and Van Basten) looked like giants there. Secondly crosses were frowned upon in the Serie A. Taibi once said that he was shocked to learn what EPL strikers can get away with in terms of crosses. In Italy the referee will call a foul the moment a player touches the goalkeeper. That wasn't the case in the EPL. Another key issue was that Milan was well covered. The FBs (Tassotti and Maldini) were such amazing defenders that could easily slot as CBs, Costacurta was fast, strong and fairly good in air himself and Rossi was a pound land but more aggressive version of Schmeichel. He was inferior to the great Dane in almost everything but he had the same aura in the box as him. If a striker dared trying to bully himself into his box then Rossi would rip his head off. I am not trying to play down Baresi contribution in the game. His job was to lead and coordinate everything at the back, his positioning was top notch (and made up for not being the quickest) and his leadership was off the charts. Gullit was once asked who would win between Milan's forward line (ie guys like Gullit, Van Basten and co) and defense during training. Gullit said that it was no contest. Defense would crush them every single time. That's how ridiculously good was Milan's defense at the time and Baresi was the heart of it. However the weaknesses were there. He wasn't the quickest, he wasn't the strongest and he wasn't the best aerially. Italy understood that as well. Baresi wouldn't become a first team regular with Italy up until Gaetano Scirea retired from the national side. Also when that defense started shaking, well, Baresi faltered. Anyone old enough to remember the last Baresi vs Vieri duel would wish to unsee it. It was ten times worse then Gaz against West Brom in 2011. A young Vieri literally owned Baresi, tossing him around, outpacing him and out muscling him. It was painful to watch.
If life was a dart game then Maldini hit the bullseye repeatedly from morning till night. He was born with great genes. He had pace, he had height, he had great technique and an almost natural awareness of how football is played that very few has (the latter Baresi had as well). He was a born professional as well. Maldini played football in his debut with the same maturity and professionalism that he ended it. He also had top coaches as well at the early part of his career such as Liedholm and Sacchi. On top of that he also had a top manager as a father who make sure his boy stood in line and of course he was one of the few players that can say that he was literally born at the club. That's because Cesare Maldini was a former Milan player whom by the time Paolo was born was an AC Milan assistant manager. I recently heard an interview of our former goalkeeper coach Eric Steele and he couldn't highlight enough the important that DDG's father was a former goalkeeper himself and how easy it was for the coaching staff to implement certain things with DDG's father having their back. Well Milan had Cesare Maldini, a club legend, who also served as an assistant manager and the manager of the club and who, by the time Paolo made his debut, he was working with the national team. Forget nepotism btw, when Cesare learnt that Paolo was going to debut he barged into Liedholm office demanding if this was down to his surname. Liedholm had to assure him that Paolo's debut was down to him being good enough. Maldini flew past through his career. He debuted with Milan at age 16, he won his place at age 17 (ironically as RB) taking his dad's former shirt no 3 and he debuted with Italy at age 19. I followed the guy throughout all his career and I can't recall him ever being humiliated.
Maldini played as LB because he could. He was two footed, he was tall, he had positioning, speed and technique. That meant that he could play in the positions others couldn't. Tassotti best position was RB cause his technique was better utilized as RB. Baresi was the leader and had to play as CB. Costacurta was versatile but he was right footed. Which lead to Maldini a guy who could play in any role, he could defend and go forward with the ball and do it exceptionally well. Hence why he was played LB.
