A) equally lucky and equally good
B) one is luckier and the other is better
I don't think we can tell by the number of roster moves a player has made, nor can we tell from one season's worth of data. At least in my opinion, the best fantasy baseball owners are those that can consistently finish in the top 3 or so owners in a competitive league regardless of injuries or breakouts/burnouts.
Number of roster moves means virtually nothing. A good manager will take knows when to make moves and when to stay put. If your in first place then I think you've done your job as a manager. You either drafted well or you made the necassary moves to improve your team.
All of the true things I am about to tell you are shameless lies
One team either drafted well or didn't have many injuries
The other guy either had a lot of injuries or was a tweaker for good matchups...
I tend to be in the middle... 3/4 of my lineup has been untouched, but in the weaker areas, I was a tweaker, looking for the good matchup or the hot bat at certain spots... I lead my my league in moves by at about double the next guy, but that was mainly shuttling players in and out of three slot, the rest was pretty much set... After some trades, I've filled some weak areas so I make fewer moves now. I'm a few points behind the leader but it's so close four of us are swapping the lead depending on that days #s, but usually, it's me or one other guy who's been in first the most. He traded two of his elite keepers to stock up on non-keeper talent, I countered by trading one elite keeper to upgrade but I had a new guy I wanted to keep for next year anyway, so one of them had to go anyway, so I traded the more well known of the two.... I'll be close.
The number of moves don't tell who's better fantasy manager than another (if the score is tied).
What makes someone better is how he handles the situation that is given to him. A manager might have had an outstanding draft with core players like Texiera, Sheffield, Harden, etc. Sheffield and Harden both hit DL early in the season and never recovered. Texiera is showing signs of improvement but he never played like 1st round fantasy draft pick. If he was able to guide his team to the top even with these circumstances, then he is a good fantasy manager.
Someone who goes through the entire season without a single set-back should be praised for an awesome draft job he did knowing none of his star and role players will get hurt during the season -- should we call that a luck?
Don't you think a great fantasy manager rises from "tough" situations? You would never call Brian Cashman a genius GM since he has all the money in the world to deal for good players. Look at Dombrowski at Tigers or even Billy Beane at A's -- they make their team good even with limited payroll budget. (I got side-tracked here a little bit).
A good manager should always look to trade and pick up FAs to tweak their line-up. No one will ever had star-studded team. A good manager will strike gold with a good sleeper pick (i.e. Liriano, Verlander, Morneau, etc.) and make good trades to keep themselves up top.
The manager with more moves could have just had 4 good SP and one open spot for hot waiver wire SP pickups. Number of moves mean nothing. One guy in my h2h league had over 350 moves and is 4th place while i made 30 moves and in first.
