Net shift: The Edmonton Oilers threw a pile of money around on July 1, but the bottom line is that the team has been terrible forever, and it landed four solid NHL players while losing mostly chaff. General manager Craig MacTavish's approach involves some risk, but it's a far better plan for a team that needs help than landing nothing for fear of signing a bad contract. The grade is improved by the fact that the worst deal (Nikita Nikitin) came before the draft and thus falls outside our timeline.
