How do you know?
Do you know the available bench players in the league?
If not, you are just making wild assumptions to fit your bias.
Going off of your math pal. So maybe you should check it lol.
And yes if you have 0 hits, 0 hr, 0 average for your catcher position you get...wait for it. Nothing. The bench player HAS to be in the lineup for their stats to count. So if this extra bench player hits 4 HRs on the bench THEY DONT COUNT. But ALL of the catchers stats will count because he is in the lineup every day.
If you don't have a catcher you can't get stats from the catcher. The extra bench player can't play every day. So you would be loosing all the stats that a catcher would provide if he was in the lineup. It's really simple man.
In a 10 team league, there is enough depth in the OF and other position players to make up 4-5 starts a week a catcher might get with streaming players. Players still able to put up superior numbers to low level catchers.
This quote is perfect. You specifically state "make up." That is it. All this will do is make up for what they are loosing at catcher. But if the still had a catcher they would have the catchers stats IN ADDITION to this bench player. Not INSTEAD OF. It's simple math. If you got 250/15/50/5 from a roaming bench spot over a season only you would have that stat line. But if you ADDED a catcher to it who had a line of 240/10/35/1 you ADD those two together. You would have a combined stat line of 245/25/85/6. That stat line is better than what only the bench player can provide.
Last time I checked, 5 starts is better than 4 starts and easily likely to add more counting stats than just the catcher alone.
The idea here is that you don't use the catcher OR the bench player alone. If you use them in tandem together you have MORE counting stats. Two players are more than one. (checks match) Yeah 2 is more than 1 my three year old confirmed.
If you ONLY use the bench player you are loosing out. If you ONLY use the catcher and don't sub in bench players for off days you are loosing stats. It's a common strategy. Managers add and drop players all the time to fill in for guys who have no games or off days.
Also something I think you are missing is that, in Yahoo at least, there are unlimited bench spots. (at least in the leagues I play in.) You could literally take your entire lineup and move them to the bench and have no active players playing in any spot. I just did this to confirm. But there is a max roster size. So I moved all 25 of my players to a bench spot.
Now answer this. Which is more. 15 home runs or 25? If you said 25 then you agree that having a catcher AND a roaming bench player in the end is better for the team.
You are so ingrained that you think you are right no amount of logical reason is going to change your mind. I suggest you drop out of fantasy baseball and move on to knitting.
