Wizard of Oz 250 Years of Freedom Road Shirt - Limotees LLC

The Aaron Donald talk has me wondering.Which positions are the easiest and hardest to play after multiple years off? Off the top of my head, I think Wizard of Oz 250 Years of Freedom Road Shirt cornerback seems like it would be the hardest. Imagining try to cover NFL WRs after being on the couch for two years sounds like a nightmare. I imagine it would be hard to keep that athleticism/reaction time anywhere close to where it was when you were playing. I feel like it be easier to return as a pass catcher than a cornerback but I'm not overly confident in that opinion. I think for the best guys, quarterback could be done if you can handle the mental aspect. I still believe Brady could get out of bed tomorrow and be a top 5 QB. He's arguably more athletic now than he was when he was drafted. I'm not asking if AD should or shouldn't return or anything like that, just asking where would defensive line be in terms of difficulty
