Written Task Option 2

Rodrigo Banes, if asked by a teammate about training hand eye coordination, would likely take the chance to pull a little prank on them. The first and easiest option would be to simply, yet earnestly, explain that you 'knew a guy,' or had some sort of facility where you had trained that particular skill in the past. Choose a location a little way from their house, enough to be a bit of a drive, but not enough to be annoying. Then, ask them to meet you there early, before pratice, maybe 4:30 or 5:00 AM. Then, simply do not show up. While you will owe them a beer and/or dinner after this, you unfortunately don't get to be there to watch them realize they've been had. 

An amusing addition to this would be to beat them there, wait for them to show up, and then chase them down the street in some sort of monster costume. This has the added benefit of being hilarious, as well as actually giving them some free cardio training.
