On a serious note!
SG-1 was made up of a Colonel with good military techniques, a brainy female officer in the US Air force, an Archaeologist and an alien. An archaeologist and a super brain like carters has no place on the front line of earths first line of defense to quote the good General Bauer. Why did they risk those incredible brains going out into missions. And they risk Teal'c who is in a sense their inside knowledge to the Goa'uld. This is a totally unrealistic situation. Why did they get to stay together? Because it's aTV show. That's how it works. And the same goes with this New guy. It doesn't matter what he's done in the past, but what he does now.
Why are you bringing Dr. Jackson into the equation? S.G.-1 is a person short. Regardless of whether you regard the replacement as Dr. Jackson's replacement or not, that place has to be filled. S.G.C. *must* have a large number of high calibre, trustworthy, tried-and-tested Americans and other humans who are more than capable of filling that place and very keen to do so. It is screamingly obvious that one does not pass over all those people in favour of a lying, thieving turncoat - not if one wishes to retain any semblance of credibility anyway.
