several factors.
in order of importance:
winning 2 games a week will give you more merch $ than winning 1 or none
winning 2 or 1 or zero is also affected by fan support which is affected by others factors ( win vs rival, tv,etc)
having a home grown team, i.e. players drafted by you
having a team comprised of players of your own nationalityt, even if you did not draft them

Here are the five team infrastructure buildings and their effects:
4. TV&Radio Station - there's no better way to build up the hype for the upcoming match than through the media! Having TV and radio shows promoting the team achievements, past and present, will result in fans buying more merchandise, tolerate losses more easily and celebrate wins longer. But keep in mind, there are limits to how high the fan spirit can rise. Additionally, season ticket sales will also have a nice boost, especially with higher levels.
5. Merchandise Store - having a luxurious store in a prominent spot will boost merchandise sales. Similarly like investing in a nice arena design, the store will take a long time to return the initial investment but after that it will generate pure profit.
When BuzzerBeater fans don't like the way you are running your team, they are less likely to buy merchandise and attend your games. Even worse, some of them will change loyalties and support competing teams! Conversely, fans will reward a well-run team with their attention, and their money. A skilled PR-Manager may be able to help fans focus more on your team's achievements, and less on its shortcomings.
Merchandising income comes from your fans buying team apparel. Jersey sales are affected by a combination of factors. One factor is whether you have a winning team. Nobody likes to wear the jersey when you're losing, do they? Other factors include how many domestic players you have on your team, and also how many were drafted by your own team, as fans like supporting local players more than imported talent. This is weighted by the overall skill of the local players, so stocking your team with local bench warmers won't do you much good. Similarly, fans from around the country are particularly enthusiastic supporters of members of their national teams, and even more so when their national team is a successful one. So, if in a given week your player played in a national team game, fans from around the country will buy their jersey, typically in a quantity proportional to their salary. National team jersey sales will vary depending on the strength of the national team, but players playing in their domestic league tend to sell considerably more national team merchandise. Finally, fans from around the league tend to notice the league leaders, particularly in important categories such as points, rebounds, and assists but to some extent in all categories. If your team has players among the league leaders, you will see a bump in jersey sales from fans of other teams in your league, with an additional bump for the most eye-popping numbers in your country or in all of BuzzerBeater.
