Had to do a one colour T-Shirt design for the BBall Elite camp this year. Went through a ton of designs because the customer had no input but only knew what he didn't want when he saw it. The worst kind of customer really. Anyway these are the basic designs I threw together. They eventually went with the bottom one but without the wings, which took the spirit out of the design in my opinion.
I've been putting basketballs, basketball nets and text together in various ways for 9 years. It really doesn't get any easier when someone says "give me some splashy designs" Especially if you're not into basketball. I included a design with a basketball player in it but I've only ever witnessed one of those accepted around here on two occasions, so it's best to stick with the ball. One of the designs I made intentionally cluttered and grungy.
