I use to be based at MSP so I know it well. Your AZO flight will be coming into the A or B gates or maybe the high end of the C gates. You're SFO flight will probably go from the G or F gates. MSP is pretty spread out and going from B to F is quite far. There's a people mover that goes from A/B gates to gate C2, then another 6-8 minute walk to the end of F. I'd say worst case scenario if you arrive at the end of A or B and have to go the end of F, you're talking a 10-15 minute walk/train ride. Best case scenario, you'll arrive in the C gates and go out of the G gates. Here you can take the skywalk from about C12 straight to G17. There are moving sidewalks all over the place too. Of course there's a small chance your SFO flight could leave from C or D as well. Kinda depends on what equipment you'll be on. They tend to put the 757's over on G and F. Delta Connection from AZO will always be at A, B, or the upper C's.
