The only reason I am not a huge fan of the restrictions is because the Brewers have ramped up their player development to an impressive degree. If this were 2014, I'd probably think, "Well it's about time MLB did something to prevent the Dodgers, Yankees and Red Sox from vacuuming up all of the international talent!!"
This being said, I think these restrictions have been a *major*consideration for the offseason transactions that subtracted Hendry Mendez, Robert Moore, Ryan Brady, Cam Devanney, Jace Avina, Brian Sanchez (he's the one that I'm actually the most curious about), Justin Chambers, and Ethan Small.
Now of course, there were other considerations, such as 40-man crunch, etc. And in addition, they've clearly added a bunch of MiLB free agents as well. But I wonder if they were feeling like guys like Mendez, Moore, Devanney, Avina and Sanchez could get back some level of value, rather than just having to release guys later. There are plenty of guys that they can/will release w/o worrying about it too much, but I think they looked down the road a year or two, and thought they may as well try to get something of value now rather than inevitably losing them for nothing later.
*edit to change - okay, you're right... probably not a MAJOR consideration.
