aTm already has 2 very highly rated safeties. BTW, how many schollies does aTm have since they (over)signed 30+ players last year. I doubt they take 3 safeties...
Collins is a corner, Harvey could do either but is likely a corner, DSG is a safety, and Watts is an athlete that could play corner, safety or WR. Last I heard, we are only planning on taking 1 more DB but we'd never turn away Brown (who is better suited to corner anyway so not sure why you are bringing up safeties).
We are targeting a class in the low 20s. And love the bit about oversigning. We didn't oversign unless you've created a new definition as we still have room both in the 2013 class and under the 85 as of right now.
