It's an interesting discussion. If we are saying 2014 as a whole, then yes, without question, Brimah was a more important contributor. But Brimah's play in the tourney is greatly overvalued by one play (he had a very good game overall, too); he was just ok in the other 5 games.
St. Joe's 9 pts 6 reb 1 blk 30 min
Nova 2 pts 1 reb 1 blk 20 min
Iowa St 4 pts 2 reb 2 blk 20 min
Mich St 0 pts 0 reb 0 blk 10 min
Florida 2pts 1 reb 2 blk 12 min
Kentucky 0 pts 4 reb 1 blk 12 min
On the other hand, Sameul's overall season is greatly over overrated based upon how excellent he was in a couple games in the tourney. For the season, TSam had 11 games where he took a DNP. They were scattered here and there so I don't think they were based on injury and the vast majority of his minutes (double figure minute games) came in blowouts. But in the tourney...
St Joe's 0 pts 2 o ast 5 min
Nova 11 pts 1 reb 1 ast 21 min
Iowa St 10 pts 3 reb 2 ast 23 min
Mich St club 4 trillion
Florida 4 pts1 reb 1 ast 18 min
Kentucky 2 pts 1 reb 11 min
So TSam had the better overall tourney, but Amida had the most important play in the tourney and had the better overall season.
