First of all, Jesus was no common individual. He healed the sick and raised the dead and convinced more than one pharisee that he was legitimate enough to let him have the tomb.
Second, you made a broad-brush statement. There were probably many exceptions to what you and Wiki believe about that.
Third, you have zero evidence that applied specifically to Jesus.
Fourth, the Gospels blow your claim completely out of the water.
Here is a less broad statement infact this is typically what happened to those nailed to the cross. From WIki:
In Roman-style crucifixion, the condemned could take up to a few days to die, but death was sometimes hastened by human action. "The attending Roman guards could leave the site only after the victim had died, and were known to precipitate death by means of deliberate fracturing of the tibia and/or fibula, spear stab wounds into the heart, sharp blows to the front of the chest, or a smoking fire built at the foot of the cross to asphyxiate the victim."
[56] The Romans sometimes broke the prisoner's legs to hasten death and usually forbade burial.
[91] On the other hand, the person was often deliberately kept alive as long as possible to prolong their suffering and humiliation, so as to provide the maximum deterrent effect.
[88] Corpses of the crucified were typically left on the crosses to decompose and be eaten by animals.
