I hope he is mentioning the following to the other GMs as selling points to drive his price up:

1. If his car breaks down, he has no problem hiking to the ballpark to make his start.
2. His mentor, Yoda, was hundreds of years old so 38 is like being a baby.
3. If he finally masters the Force, then you don't need to worry about his arm because he won't even be using it.
4. His last name creates so many funny bits on local talk show radio.
5. His philosophical post game interviews makes you feel good about yourself and life so you actually forget how bad your team really is.
6. He won't be suspended for using PED, since you don't need them to throw 65 to 80 MPH. Although, he may be busted for using pot.

anything else that I am forgetting that may help Sandy sell RA?

I think Dickey might be a pot smoker. In fact, I would be surprised if he wasn't

In all seriousness, other minor (very) selling points are that he fields his position very well and he holds runners on great

RA is the most interesting man in the world! Stay thirsty my fans!

7) His At Bat Song is the Game of Thrones Theme, that alone should get an extra prospect or 2.

See that, now we are cooking.
I almost forgot since he could pitch every day, why can't we trade him to all 7 teams that want him? We could get the best prospect from each team. This will be the first 7 team trade in history with 1 guy going to all 7 teams. Think of all the airline miles he would rack up.

We need a little levity since all this speculation is driving me nuts.

8) They can put him out to stud and breed an entire rotation and BP of UCLless Pitchers, Just think 20 years from now having 13 pitches who never have to worry about having to get Tommy John Surgery!

Heck, the royals are used to waiting 20 years, we may be able to get their whole farm system.
Nice one.
