Well, we can transform these sentences into symbols.

Lets say

A = "team wins"

B = "team remains (stays) in the playoffs"

C = "championship is in reach"

So, we have A -> B, B -> C and [(A -> B) AND (B -> C)] -> (A -> C).

So, construct table with columns A,B,C, A -> B, B -> C, A -> C and [(A -> B) AND (B -> C)] -> (A -> C) and put every value true or false for A,B,C and fill A -> B, B -> C, A -> C and [(A -> B) AND (B -> C)] -> (A->C) according to logical rules.
