The NBA and NHL Drafts went down this week, reloading each league with a flood of young talent.

Oklahoma Sooners stud Blake Griffin was first overall in the NBA Draft, finding a new home with the Los Angeles Clippers after sweeping the Player of the Year honors in the NCAA.

In the NHL, London Knights star John Taveras was selected as the top dog by the New York Islanders after leading the OHL in scoring and setting the league’s all-time goal record with 213 career goals.

Both athletes are phenomenal talents headed to franchises in need of total overhauls. Sometimes that’s a good thing, but it can also spell doom for a top prospect. The weight of a waning team can be too much to handle in the first few years.

So with that in mind, which No. 1 pick will have the biggest impact on their teams’ future?
