I'm have an opportunity to shoot a reserves game next week at St Andrews. 
I will probably mainly use my 200mm 2.8L (obviously 70-200mm would be much more useful) apart from that i'm not sure whether i should bother to bring any other lenses (e.g 24-70mm) there is also a possibility of renting a lens for the day, but that is gonna generate cost, and i won't be recieving any money back for the photos i take, i'm not sure whether its worth it.
What do you think, will my 200mm get me sufficient shoots if i position myself well?
Or would you recommend forking out for a rental?

very good point. i know already that i would love to "obtain" that lens, but my current photography income can't justify buying it......yet!
