The Twins are the only team I know of that perpetually signs nothing but #5s. It's not just that they won't sign aces, they won't even sign #3s (apart from Ervin Santana, who worked out very well and played as a #1/#2 for most of his time in MN).
For every #5 that turns into a 1-year wonder (Pavano, Hughes), there are half a dozen complete flops, and those 1-year wonders end up causing headaches when the Twins lock them up for more years before they crash back down to earth.......
Have to give it to the fans who stay optimistic about this stuff, but come on. If the Twins are good this year it won't be because of Martin Perez.
No team ever has a good year, merely because of their #5 starter. It's not Perez's fault he's not Kershaw. Take this move for what it is.
