Enscheff, this is an honest question because I'm trying to figure out how these opinions jive.
You have stated we should always sell a controlled pitcher with 2 years left to maximize value, yet you have also suggested that it is fine to buy at the deadline if you are contending. If you believe it's wise to sell early to get pieces back even if you're a good, contending team, why are you also ok giving up pieces to go get a similar player at the deadline?
A contender should never sell at the deadline. Period.
A non-contender should look to sell any pitcher at the deadline if they have 2.3333 years or less of control remaining (like Gray now).
A contender should look to sell pitchers with 2 years of control left in the offseason (like the Rays dealt Smly).
If a pitcher with 2 years of control remaining is coming off injury, they should keep him to prove he is healthy, then trade him either at the deadline (if not contending), or in the next off season (if contending).
If a guy is coming off 2 consecutive years of injury, and the team is forced to use him in his last year of control, use him up and let him walk as a FA.
Ideally, the system will produce 1 pitcher per year. The rotation will look like this:
Rookie(s)
5 years control
4 years control
3 years control
homegrown pitcher recovering from injury
FA stop gaps should be signed to fill any holes. These FA stopgaps should be pitchers like Colon and Dickey signed to 1 year deals, maybe with an option. Never spend more on FA pitching.
The Braves superior resources should allow them to sign better FA stopgaps than the A's or Rays are capable of signing.
Guarantee no pitcher any money through his 20s if his 20s are already controlled (Folty, likely with Wright, Sims and Newk). Maintaining the ability to cut them loose at no cost is important.
Extend any promising pitcher if his 20s are not controlled, buying FA years up to and possibly including his age 30 season only (Teheran contract, likely with Soroka and Allard). Gaining control of these FA years in their late 20s is worth assuming the risk of guaranteeing seasons in their early 20s.
I think that pretty much covers all possible scenarios. Use them up, and ship them out. That's the most efficient way to handle pitching assets and maintain long term competitiveness.
