It's time to give Ed Davis a chance
Bargnani is what he is at tis point. An inefficient, high volume shooting non rebounding, defending power forward. He's been like that for the vast majority of 7-8 seasons in the NBA.
Ed Davis is in his 3rd NBA season and his having the best season in his career and plays consistently at a high level almost every game. To this point in his career he is still an unknown an is producing. It's time to ride with Ed Davis.
