Thought experiment! Let's say that the Twins were so taken by the 2006 squad that they decided to keep each player from that team as long as they were good enough to play professional ball. In this experiment, we could think of all the Twins' players as restricted free agents where the team would always match the offer sheet. Looking back at that squad, there are a bunch of guys who make next to nothing these days (or are out of baseball), but there are some pulling down big money. The list, by 2012 guaranteed compensation:
$24M -- Santana
$23M -- Mauer
$18M -- Hunter
$14M -- Morneau
$11.9M -- Lohse
$10M -- Cuddyer (est, full contract is $31.5M over 3 yrs)
$7M -- Kubel (est, full contract is $15M over 2yrs)
$7M -- Nathan
$7M -- Garza (arb. estimate)
$6.5M -- Baker
$5.5M -- Bartlett
$5M -- Liriano (arb. estimate)
$4.5M -- Crain
$3.75M -- Guerrier
$2M -- Silva (yes, the Cubs still owe Silva $2M next year)
$1.5M -- Punto
$1.5M -- Perkins (arb. estimate)
$1M -- Casilla (arb. estimate)
So that's $153M for 18 players (but 17 active players.) Figure about $1M/player for the last 8 spots on the active roster and $400K/player for the 15 spots left on the 40-man, and that gets you to $167M for a full 40-man roster. If you figure that Blackburn and Span make the active roster, then you're up to about $173M. I'm not sure how many wins that team would be expected to win, but at first glance I wouldn't be too optimistic.
Of course, if the Twins had managed their roster this way, Luis Castillo would never have been traded and we wouldn't have gone through the Drew Butera experience. Maybe that's worth $173M all by itself.
On the plus side, Santana earning $21.6 million and not pitching at all last year might finally have made a bigger target than Mauer.
I wish my dad, who complains bitterly every time the Twins allow any half-way decent player to leave, could read this.
