My major piece of advice is to join a league that uses standard rules and categories. You want to be able to seek out advice and information that applies to you - and if the commish thought “it’ll be fun to completely change everything!”, you’re not going to be able to do that. So that means finding a 5x5 Roto league.
“What’s a 5x5 Roto league?!?”
5x5 refers to the number of categories. Five categories for hitters, five for pitchers. Traditionally, those categories are:
Hitters: Runs, Home Runs, Runs Batted In, Batting Average* and Stolen Bases
Pitchers: Wins, Strikeouts, Saves, ERA** and WHIP***
“Okay, makes sense. What’s ‘Roto’ mean?”
It’s short for Rotisserie, like the chicken. (Fantasy baseball was concocted by a bunch of guys who hung out at a restaurant called La Rotisserie Française.) What it actually means is that you are assigned a point value for however well you did in a given category relative to the rest of the league. Example: You’re in a 10 person league. You finish the season with the most Stolen Bases. You get 10 points. The guy below you gets 9, on down to the guy who had the worst year in Stolen Bases who gets 1 point. This is repeated for all 10 categories.
“So how do I get Stolen Bases, or any other stat for that matter?”
When the league is created, the commish will determine what roster spots will be used. Usually, its a Catcher, 1B, 2B, 3B, SS, 3-4 Outfielders, 4 Starting Pitchers and 3 Relievers. Some variation is allowed - but again, don’t get too crazy, or things get wonky (an extreme example would be a league that doesn’t use catchers, or has 3 Second Basemen per team - like I said, wonky). Whoever’s in your starting lineup each day has their stats added to your yearly total. Most leagues allow you to change your roster every day. Some are weekly. Each have their own individual strategies involved. I like daily - but there’s nothing wrong with weekly.
It should be noted that you’re (usually) given a limit of 162 games per position, and 1350 total innings pitched. Some roster flexibility is needed to hit those maxes (nor is it necessary to hit them), but you shouldn’t get that flexibility at the expense of your starters. If your starter doesn’t have a game that day (or is being benched for some reason), you don’t lose a game unless he plays in that game (even as a pinch hitter).
I’m going to hold off on drafting advice. That’s a WHOLE other kettle of fish, and is very league dependent. Since you’ve never done one before, I STRONGLY encourage you to sign up over at MockDraftCentral.com and do a mock draft or two. It’s a free site, there are drafts going on constantly, and you can jump into a league that looks like something you’d sign up for (it’s a mock draft, so you’re not obligated to anything beyond the draft).
*Batting Average as a category - I think a beginner could easily make the switch to a league with On Base Percentage, as long as they keep that in mind both during the draft and during the season. It changes a few dozen players’ value dramatically, but is a much more prevalent category these days.
**ERA - Earned Run Average
***WHIP - Walks + Hits / Innings Pitched
