At the end of the day, if we want him, we're going to have to pay legitimate money for him. That's it.
Giuntoli deserves the benefit of the doubt. If he thinks Calafiori is worth investing in, and we can sustain that kind of financial investment, great. If he doesnt, there is probably a good reason and we should accept that.
After years of spending big money on players and looking for cheap alternatives to fill out the rest of the squad, I hope we learned to not go crazy over the flashy/expensive names if it comes at the expense of actually building a team.
