Who would u take at 2b polonco,kelly johnson, mark ellis or ty wiggington?

Polanco is the only sure thing and will give a great ave. (should hit.330 ish) and will score a ton of runs (100-110). He wont provide any power and wont have huge RBI numbers but the other numbers are extremely good. Kelly Johnson has the potential to hit 20HR and drive in 85-90 runs and should score around 90, the question for him will be whether or not he can hit .280 or better. So either of those 2 depending on your needs, the other 2 are fantasy backups at best and are nowhere near Polanco & Johnson fantasywise.
