If he comes at a decent price...and is an upgrade over Kolo and Spencer, then sign him...otherwise, save our money for some more OFFENSIVE firepower...ideally WRs!!!
The Vikes need to upgrade at NT because Pat is getting older and slower, so he needs to be rested in games more often each year.
Scott would provide him with rest on each series, and should be pursued in free agency before the draft.
The reason is to eliminate one more 'need' before the draft to provide the Vikings with extra flexibility to trade up for a key remaining need; e.g. WR or QB.
