How many times have the Brewers been unable to sign a 1st, 2nd, or 3rd round pick? Covey (and that wasn't a money issue) is the only one that comes to mind in recent years although I know there have been a handful over the last 30 years.
I am in the same boat. I like reading up on guys we pick but I have never been disappointed at missing out on one guy or another. I do think Melvin reached a number of times because the system needed pitching. But even saying that I still got excited about a guy like Arnett's potential.
According to Fangraphs, Arcia's got the third highest defensive WAR among all shortstops in baseball. His D is elite. If he can just be adequate on offense he will have tremendous value. He's only 22. Give him a few years and you'll probably have an outstanding player at a valuable position.
I really wish Ortiz didn't remind me of this guy: http://imgs.globovision.com/WGsXQBgwLcfQ9nJYClpVqDcP-Ls=/847x0/smart/3bec7350aa2e4cc0867f4a738a35cba8
