What are you talking about control? Archer has more control than either hitter on the Cubs while being more productive (200 innings, sub 3.5 FIP) at a higher value position.
Also, baseball reference has him that low by Fangraphs doesn't so I have no idea why baseball reference has him that low but it makes no sense to say he was a two win pitcher. Even if you wanted to average out baseball reference and fangraphs, he'd be at 3 and that would be more normal. No one thinks Chris Archer is a two WAR pitcher.

All I'm saying is he had 1 season over 3 WAR. That is it. We might be over evaluating him based off of this and are too wrapped up into his SO's. Stroman maybe a better option. Younger and a upward trend vs a dump.
You mentioned Q.
2013: 5.4
2014: 3.5
2015: 4.0
2016: 5.1
2017: 2.4 (combined)
It is not the same level of talent at all and he cost a top 20 and a top 90. And to be honest 2x the accumulated WAR in the same time frame.

one extra year of control.
Now tell me that both are even close in sale value?
Now on control it is more about adding control and then freeing up more short term contract with that added depth to acquire more long term contract. I'm not bothering to look deep into it as I feel it is pointless.
