I agree these are off the top of your head, I do not agree they are not debateable: 1. If we assume a 10% inflation rate, in order for other payroll costs to go up $5-6M over 2009 (last yr in the dome), other payroll would have been $50-60M in 2009. That's...high. Way too high. That would be most of their "other" expenses in 2009. Some quick, back of the napkin calculations (guesses)--extremely generous ones at that--puts other payroll in the range of $20M. And by generous, I mean generous...I estimated no employees at less than $50K per year, for example, and have 20 at $150K or more (including $2M each for TR and DSP). So a more reasonable estimate (and 10 percent over the past 6 yrs is in itself generous) is $2M more than 2009. I'm not sure what you mean by "additional personnel to run documented beefed up operations", but let's go with it. $2m more. Although, to be fair, they were in the Dominican before 2009, they've been in Ft Myers forever, so that's a pretty nebulous additional $2M. That would be 20 extra employees at $100K each. 2. In 2009, the Twins paid the 22nd pick (Gibson) $1.85M. In 2015, the 22nd pick cost Detroit $2.15m. Rule 4 draft costs are capped now, so an argument can be made the Twins have LOWER cost risks for the draft now than they did in 2009. For example, Stephen Strasburg cost the Nats $15M in 2009, number one pick Dansby Swanson cost the D'backs $6.5M in 2015. We'll say, generously, the Twins can expect to be exposed to an additional $1M on average per year, although again, I think that's generous. As for adding international FA's, there is now a cap, based (like the draft) on your W/L record the previous year. In 2015, the Twins, with the 6th most money to spend, had just under $4M. They spent more than that in 2009. So add $1M per year. Again...generous. 3. Operating costs for TF are tough to estimate. I think you're high, but I really can't find any confirmation one way or the other. The Twins themselves, in lobbying for a new park, estimated "in excess of $10M". http://minnesota.twins.mlb.com/min/ballpark/new_banter.jsp?content=qa Let's split the difference...$15M annually. Take away the costs the Twins were paying in the dome anyway...office furniture, phones, internet, office supplies, etc etc etc. We'll say $2M. I can't find what the Metrodome lease cost the Twins in rent, so I'll say zero. Make it $13M. 4. This year the Twins will spend $5M on renovations...the most they've ever spent. http://ballparkdigest.com/2015/10/26/cf-improvement-on-tap-for-target-field/ So it hasn't been "$5M every year, some years more." It's been less every year. In fact, it looks like they've spent around $11M total on renovations, or less than $2M per year. And most, if not all, the renovations have been designed to increase revenue. So I'll give you $2M per here, but in reality, they probably MADE money on the deal. 5. The Twins opened their Domican Academy in 2004, so I'll need more than your word for it their expenses have increased greatly in the last 6 years. I'm not sure how they could be spending a million more, but I'll give you a million. The Twins have been holding spring training in Ft Myers forever, I'm not sure where you're getting huge increased costs. According to this: http://ballparkdigest.com/2015/10/26/cf-improvement-on-tap-for-target-field/ the entire cost of renovations was paid by Lee County. The Twins are operating a dorm now, but surely they decided that was cheaper than rent/per diem. Call it a wash. Total, $1M Add it all up, with very generous estimates, and I come up with $21M. If I was conservative, more like $12-15M. That leaves a lot of space.
