Choose one: Mack or Donald

Let's say Lovie wants a new toy for his defense. There's an early run on OTs, or QBs. The Bucs find themselves sitting at 7 with Kalil Mack and Aaron Donald still there.I believe both could serve us well, and be moved around the field in multiple positions. Both supply pass rush. Who do you pick?I'd love to watch Lovie work with either, but as much as I like Donald, I would probably choose Mack.
