Answer:
Not really sure what you're asking, but if you want me to correct the verb tense and change the sentence, I can help you.
The sentence would need to be changed to: "The players drank the water that they took to practice."
Step-by-step explanation:
You would need to change the verb phrase "Have taken". That phrase is still past tense, yes, but it's past past perfect tense. What you need is past progressive tense. Hence the word "took".
