The way I see it, is that running is not very sport specific and does little for coordination, balance, agility.
Using various drills / exercises you can easily target the same components of fitness but get the added benefits of increasing coordination, balance, agility and various strength components.
With young amateurs that only train 3-4 times per week for an hour or so I think it is important to get as much bang for your buck as possible and in this case running doesn't cut it.
Running is very specific to Boxing.
