Like watching the player you bet on doing the same thing over and over. You don't need to name names, but here are a couple of examples:
1) The hopeless kill shot. Sure, sometimes when your back is to the wall you have to fire one rather than give an easy setup. But, what about those blasts into the pad or the wood when it's not needed?
2) Endless catch and return. It's nice to be able to catch, isn't it? But, how about some offense once in a while?
I'm sure you can expand on these and add some of your own.
