If you are starting a team in a new dynasty league, take a look at the position breakdown of the top 200 players, using the main position for utility players except for one, who plays basically any position in the field.
What quickly jumps out is the lack of depth at second base and third base. The second and third base positions alone add up to only one more Top 100 player than the shortstop position. There are some great players at those two positions, but the overall quality lacks compared to shortstop or first base.
When it comes to catchers and relief pitchers, I can tell you right now that there are few of them ranked. There are a lot of good catchers, but many of them will get only 110 or so starts or they are getting up in age, making them less than desired dynasty options.
As for the relivers, I never chase saves (or holds if your league has them). How many players dread chasing Aroldis Chapman last year or a host of other top closers? Meanwhile, five new closer will come out the woodwork this year that you can get in the middle of the season.
Please, blog, may I have some more?
