The football gods can be a fickle bunch when it comes to separating the injury prone from the ironman.
"There's an awful lot of luck involved," said Vikings tight end Kyle Rudolph, who will become the 50th Viking to reach 100 starts in franchise history when the Vikings play at New England on Sunday.
He should know.
When Rudolph suited up for the 2014 season finale, the 2011 second-round draft pick had missed 15 of 31 games since his 2012 Pro Bowl season.
"Basically," he said, "I played only one season over two seasons."
He was injury prone. But it wasn't anything he did wrong.
He ate right. Trained right. He studied the habits of durable players. He talked to them. He got to know former Vikings tight end Steve Jordan, whose 149 starts from 1982-94 ranks 16th in franchise history.
"I did everything I could think of to stay healthy," Rudolph said. "But in '13, when I missed the last eight games, I broke my foot scoring a touchdown in Dallas when a guy misses the tackle and lands on my foot. That's bad luck."
