Based on discussion earlier in the thread regarding having a striker who scores 20+ goals a season or having multiple players chipping in, i looked at the stats from the PL era from the title winning teams and see if there are any clear relationships made from either of the two scenarios.

- # of seasons in the PL ear where the top scorer for the champions has scored <20 goals is 11 which is 46% of the times, however since 2010-11 all title winning sides have had a 20+ goals scorer
- # of seasons where top scorer has scored <27% of all goals for the champions is 15 which is around 63% of all seasons
Top 2 Scorers

So it seems like you can win PL titles whilst having either a 20+ goal scorer or spreading the goals across the team.
