Why is this relevant? The man said he was going to spring training with the Texas Rangers.
He doesn't need to do this. In fact--he shouldn't do it. Wilson just finished a nice, long football season--time to take a vacation! He isn't getting paid the big money yet since he was a third round pick, but I'm sure he can afford to head down to Punta Cana for a month (besides, it's cold in Seattle).
Along with taking a break and getting some much needed rest and relaxation it isn't a smart business decision. The word is that he just wants to keep open and maintain a relationship with the Rangers and MLB, but he can do that without playing baseball.
Yeah, playing would be fun and as a former player he is not going to suck at it. However, he has set the stage for a huge pay raise. The last thing he needs to do is strain a muscle or tear an ACL diving for a line drive.
If he isn't planning on actually playing--well than he should go. Playing is a bad idea, but if he just wants to hang around a MLB team for a while he should go.
