But is it true?

I don't know about for the rest of the league but for Snead, those type of safeties do seem to grow on trees.

McLeod
Joyner
JJ III

That's 3 safeties in 4 years who can all cover very well.

Contrast that to the last time the Rams had a WR with Sammy's skill set.

I'm sorry but WR's with elite skill sets are more rare than safeties who can cover.

If that safety skill set was that rare OR the safety position was as important as WR, those guys would be paid more than WRs. The franchise tag wouldn't have been $11M; it would have been $16M like it is for WR.

So... either the skill set is not as rare as they're saying OR the position itself is not as important. Pick your poison.
