A fun little exercise to kill time. I (or down the line someone else) picks a pair of players who are competing for a position. You say who you keep and who you trade and why.
To start it we'll go with the most obvious one, IMO.
Jace Peterson vs Jose Peraza
Before someone says we can keep both, we really can't neither hits enough for 3B. Sure we can do it, but it will be certainly disastrous for our offense to have a non-power not really great hitter at 3B. Build your case including present value, perceived value, etc.
