The whole, "Why not? It can't hurt" sentiment is wrong. There are very few things in the world that are outright wrong, but this is one of them.
If you bring in a guy like him, it sends a very clear message. We don't care how hard you work or what you have done. This guy is going to come in here and take your reps away from you because despite a lot of evidence to the contrary, he may possibly under a lucky star be better than you.
So tell me how bringing in a guy totally unfamiliar with the offense, age 34, known as a 'problem' to compete with a guy who outclassed him in every category sends a good message?
If you work hard, perform better and act like a decent human being, it doesn't matter because this guy is a name fans have heard of before! If there is justification for bring in a guy to compete, then great. There is absolutely zero justification for bringing him in..
