Grammatical issues of the question aside, I will answer this. I am a Lions fan and would be incredibly disappointed if we took Stafford. Football Outsiders did a great study on quarterbacks with Stafford-like numbers in college and only Matt Ryan panned out (and his sample size is only 1 year). Stafford is too inconsistent and not a sure enough of a thing to drop that kind of money into.
Can't take Curry, despite the "sure thing" status. The Lions only LB need is a natural MLB, which Curry is not, and Sims and Peterson can't move inside either. Also, too much money would be spent on the LB position.
Jason Smith is the pick. It allows an over-matched Jeff Backus to move inside to guard and provide some OL stability for the upcoming years. It might be a boring pick, but it's the right one.
