I think you're spot on with all of this. Murphy is what we hope Kipper can turn into, an undersized 4 (yes I said it) that can use his strength and motor (which seems to be not firing on all cylinders lately) to clean up the boards and score a lot of points in the paint with the threat of knocking down a 3 now and then. We don't really have an answer for Lynch except try to get him in foul trouble.
Coffey is a different animal to deal with too. He's long and likes the perimeter a lot more than going inside and banging and they really don't need him to do that when Murphy and Lynch are in the game. He's going to be tough to defend, I could see Alstork spending a lot of time on him even though Mark is several inches shorter. Coffey likes the open court and I think Alstork could frustrate him with his in your face defense.
We need to be on our game tonight, Minnesota is pretty tough in the Barn.
I really don't see how you can call Kipper a 4 in Underwood's offense, to me he seems like more of a 1 or a mix between a 3 1/2 or a 4 1/2.
