Having some taller more physical players in the Secondary with enough speed to cover is the way to go. Lacking a 1st round pick and having many secondary needs to fill requires that we think outside the box somewhat. These guys can be intimidating to some Wide Receivers and cover the bigger Tight Ends.
Coming into last Season Some top bigger Secondary players who were highly taught-ed were :
David Amerson CB NC State 2-3 round projection
Ray Ray Armstong SS Miami 6-7 round projection
T J McDonald FS USC 4-5 round projection
Now, due to some tough seasons and some personal issues (in Ray Ray's case) These guys are no longer in the spotlight. Therefore, now they would easily be attainable in the draft. I think drafting a trio like this and coaching them up would pay huge dividends by the season's end and into next year and beyond. Yes there is some high risk/reward to this idea but I think it would be worth it even if only 1 of these guys regains the form it was once thought they all had.
