Dude, I went undefeated Season 5 while in IV, my first full season after taking over my team in Season 4 with less than 11 games left and slipping into the playoffs.
Got promoted to Season III where my team was severely undertalented compared to the rest of the league and yet with persistence, determination, and a desire to not fall to the 15 underlings beneath my Greatness, I manage to make the playoffs every season. I study the league and the great teams of BuzzerBeater. While I may not exactly be a GOAT like my team name suggests, I enjoy the challenge of competing against the upper echelons of this league.
I've been here since Season 6 and have managed to build a few rivalries worth noting, in particular the WEAKLING that is known around these here parts as The Illusion. ;-)
It takes time and you have to be willing to go through the struggles. Just don't expect to come in here and be successful. You have to keep an open mind because most of us have been here a long time so we are expected to have the money and the resources to field a more competitive team. It's going to take dedication to learning this game and learning your team this deep into BuzzerBeater's life to field a team that can not only compete at II and maybe NBBA but also at III.
