On one side of the line but the question is, which one. Keep in mind that if Long walks at the end of the year, his replacement is already on the roster.
I think we have had this conversation before and it is still the same problem.
Move Martin to the left and then you have to fill the RT position. Fins are thin at T, but maybe you could move Garner to RT or Jerry to RT and Garner at G. Either way, it is going to be a problem and disrupt the line.
However, I must say, the more I think about your idea, the more I like it. Think maybe getting a 1st is overly optimistic, though.
Here is the roster sorted by pos. and there are not many options.
