Totally fine with it, especially if they turn around and flip Quentin to an AL team like the Blue Jays or Indians (where he can DH) for a B- or C-grade prospect.
Kimbrel's a luxury on a bad team, and his arm was a ticking time bomb. More importantly, the Braves have rid themselves of Upton.
Maybin is a very good defensive CF on a team that really needs one. He's probably their 4th-best hitter right now, which says how bad their lineup is.
Quentin will be gone pretty soon. He's better than Jonny Gomes, but with the money he makes, he's not worth it to the Braves if he's going to blow a knee by Memorial Day.
Wisler is the Padres' No. 1 prospect (No. 34 overall according to Baseball America) and reached Triple-A last year. He'll probably be the Braves' No. 3 starter by June.
Paroubeck was a 2nd-round pick two years ago and is only 2 years out of high school, so he's 3-4 years away. Too early to tell.
