Just a quick Google search tells me that while a player in a complex league makes a minimum of $4800/yr, the Chicago Dogs pay a salary range of $52k-$96k for a season. I don't know what level of play they are, but that's quite a jump.
I'm intrigued by a player like Matt Hogan, who finally hit consistently at Oral Roberts in 2023, looks like he went undrafted, played a year with the indy Pioneer League Rocky Mountain Vibes (Glassdoor says they have the same salary structure as the Dogs), and now, this year, after signing with the White Sox, jumped to age-appropriate Birmingham, and is OPSing .774.
