I mean, there's really not a dumber thing you could say then 'Kovalchuk leads in giveaways because he tries to do everything himself'. Most giveaways are passes, which is why someone like Joe Thornton is always among the league leaders. It's also an incredibly dumb stat.
Kovalchuk is -7 with the Devils at 5 on 5. He is also not -41 with the Devils, might want to check your numbers there. Goalies being hot garbage never helps.
#2 is also one of the dumber things you've ever written on here.
