If Parker shows up healthy, in shape, and hungry, he's worth a spot in our rotation. He's only 25 and has been a legit scorer in the past. He has a true PF's game with some nice offense inside of 15 feet, a unique game we don't have a lot of otherwise. You can watch his highlights and see he has some really quick feet compared to Grant, who looks like he's moving in wet sand.
If you can trust his health, he can no doubt help us. I don't think we can genuinely make the case that Edwards, Williams, Fernando do a lot for us, barring a number of simultaneous injuries.
