I'd say no, too. If I hadn't seen Strasburg sparkle like he did in his short time here, I might think about it. But Stras has the potential to be an hall of fame worthy himself. Hell, if he can do over a career what he's already done with the Nats, he's probably an all time great - maybe Halladay level.
Harper is more difficult to cheer for - for me, anyway. Just seems so cocky. And we'll probably end up trading him to the Yankees no matter how good he is. But we'd still get like 5 good years out of him.
So I'd probably say no, as monstrously good as Pujols is.
