4     66777     Bob Terry     Spurs     99     (99 for Spurs)
5     66331     Charles Smith     Jazz     13     (13 for Jazz)
Desired Output:
1     66489     Chris Terry                     Nuggets     21     (2 for Kings)
2     99999     John Smith                     Lakers     28     (16 for Bulls, 4 for Pistons)
3     55455      Bob Johnson                    Rockets  6     
4     66777     Bob Terry                     Spurs     99     
5     66331         Charles Smith              Jazz     13     
Details:
- Sequence column is the sequence number of which team the player currently plays on, meaning the if a player was trade or switched teams like John Smith, the highest sequence is the players current team, so the Bulls was his first team, Piston 2nd, and Lakers current (since the highest sequence number)
-If a player changed teams (returns in more than one row of results) I would like:
A) current team listed as Team, so for John Smith above it should be Lakers
B) in perentesis, he should have his first team listed 1st along with point total scored on that team, 2nd team second w/point total and so on....
Like: John Smith Lakers 28(16 for Bulls, 4 for Pistons)
Not sure how to change my query around, thanks.
