A bigger reason was because the Nats were the only team that drafted him.
he was committed to UCLA. After the elbow concerns came up, the UCLA coach said he was better off signing with the Nats because of their medical program. giolito's folks even said it was the treatment of stras that led them to forego the scholarship. They could afford TJ if he needed it, but the JZ / Strasburg rehab program convinced them he'd be treated better here than by a college. Had it been some team other than the Nats, you could see him going to school, like a lot of kids, getting the TJ, and being better than a 16th pick when he came out.
