Let's not say there's "zero risk" with signing Barry. There is plenty of risk, although it's likely minor. Facing federal charges, you may pay for a player that spends more time in a courtroom than on the field. His defense is a liability for NL teams. He has a locker room presence that may not jive with the existing team. He's 45 years old and his body could break stepping out of the batter's box (Nomar). It's not as easy as saying, "Barry is good, let's go get him." Rather, let's say that the risk may be worth the reward, but it's not guaranteed.
And just because his agent said he'd offered Barry for the league minimum that doesn't mean A) that it happened or B) that the Union would allow him to do that. It's not as easy as calling twelve teams and saying Barry's available for a song.
