This year is friggin' crazy. Perez started the year pretty poorly, and it took him a while to get his head together. But he's hardly dead weight as it stands now. Do you roll the dice on a rookie? Is he going to be that much faster than Perez? That would basically be banking on him being Button fast out of the box. Even if Magnussen is Lewis Hamilton fast, he's not going to have the testing time to work his way up to speed. He either turns out to be a Formula 1 prodigy, or he'll flounder. I could see them plonking him on Marussia with a mid-season option to pull him up if Perez is struggling. But that'd be about it. Putting him in a race drive for what should ostensibly be a top team seems like a bit of a hail mary move. I don't think McLaren is that far gone yet, even if they are sweating without Hamilton.
