[1] His playing ability along with Danny Ainge and Greg Kite led to the success of the BYU program during this time.

[5] Almost immediately after matching the offer, the Jazz traded him to Boston for a future draft pick[6] and two Boston-Utah preseason games.

The highlight of his time in Milwaukee came in Game 4 of the Eastern Conference semi-finals in 1989, in which Roberts replaced injured forward Terry Cummings and scored a career-high 33 points in a 96–94 loss to the Detroit Pistons.

He then signed a 10-day contract with the Cleveland Cavaliers, and was immediately put to work due to starting power forward Tyrone Hill going down with an ankle injury.

[10] Once Hill returned though, Roberts stopped seeing playing time, but considered his stint with the Cavs as a stepping stone.

The following year, he signed a one-year contract with the Dallas Mavericks,[12] but was released almost immediately after Don Nelson became General Manager.
