Not sure their is going to be any agreement on that one. Though he had KG and for a few years Marbury until Marbury's ego got in the way they had the makings of a good team. Though Brandon was a good PG, he was often injured and his status is what kept the TWolves from committing to Billups. Here is Billups Wikipedia write up, some of which directly quotes him.
"Billups was drafted third overall in the 1997 NBA Draft by the Boston Celtics. He did not mesh with new Celtics head coach Rick Pitino. Years later, Billups reflected on his stint his Boston, commenting, "That didn't help. That didn't give me a chance to really slow down and listen to myself, listen to the game and what's going on. I never really had that chance. It was a recipe for disaster there." In addition, the Celtics coaching staff did not know whether to play him as a point guard or shooting guard. 51 games later, Billups was traded to the Toronto Raptors in exchange for All-Star point guard Kenny Anderson on the last day of the 1997-98 NBA trading deadline. After a few months, Billups then played for his hometown Denver Nuggets, who traded him to the Orlando Magic. He was on the injured list until season's end due to an injured shoulder and never played a game for Orlando (he was included on the season-ending team photo, wearing jersey number 2). Among NBA circles, Billups was considered a draft bust.
Billups was signed by the Minnesota Timberwolves as a back-up to then point guard Terrell Brandon, who would mentor the troubled player alongside Sam Mitchell and Kevin Garnett. The two would work on shooting, scouting, decision-making and the other attributes that came with playing point guard in the NBA.
During the 2001-02 season, Brandon suffered a serious knee injury. Billups replaced him and had a breakthrough 2001–02 season. Timberwolves won 50 games before they were swept by Dallas in Round 1 of the playoffs, with Billups averaging 22 points per game in the series.After his breakthrough season, Billups became a free agent. Billups had wanted to return to Minnesota, however the Timberwolves were engulfed in salary-cap issues and wanted to see how Brandon would respond to his knee injury.
In June 2002, Billups signed a six-year, $35 million contract with the Detroit Pistons to be the team's new starting point guard.[4] When he signed with the Pistons, he was forced to take the number 1 because number 4 was retired in honor of Joe Dumars. Billups quickly earned respect from Pistons fans and colleagues for his tenacious defense and clutch shooting."
I will say the write-up does give a good amount of credit to Brandon helping him along with KG and Mitchell. Anyway, when Billups got to MN, he was a mess.
As for Sealy, in 8 years he was with 4 teams, the TWolves being his last. Over his career he averaged 10.1 Points per game.
Anyway, the crux of the matter concerning Flip's time with the TWolves is that I feel Flip got as much as he could from the talent he had. I am not sure spectacular is the right word, but I do fail to see his time coaching the TWolves as dissappointing, given the amount of times he made it. And though most of his playoff appearances were one and done, especially since he almost always came up against the Lakers, it was obvious from the play he was not given the overall team talent to succeed.
Given no other TWolves coach has gotten the team anywhere near the playoffs, that seems to be pretty respectable IMO.
Anyway, personally I seriously doubt NT is going to hire him. My point is that he is a legitimate fall back option and does bring some benefits both as a coach and someone many concerned with the BB program could get behind. Along with that, and truly this is just me, but he could very much be a father/mentor figure for the kids.
Peace Bro!
