Big 3? Odd seeing the picture just shows the Twins; no Ryan. Anyhow, I never really thought of them as the big 3 even though we say RPG a lot, but Ryan is the one that moves to other lines.
Personally I think Ryan is the safest of the 3 given Getzlaf and Perry are due for new contracts and Ryan is still signed at a pretty good deal for 3 more years.
I can see that Getzlaf may want to stay given that his wife has family in the area and they are expecting their 2nd child soon. Perry, on the other hand, seems like the one that could that could leave for a tight budgeted team.
