Last year we mostly played a "field" and "boundary" safety. Smith was usually to the short side of the field (closest to the sideline) while Stafford was usually to the wide side.
I think I remember reading that verbiage and concept mentioned in an LJS article a while go. Thanks a bunch for reminding me. As such, I agree with whateveritis1224 that projecting for a traditional FS-SS split doesn't seem to be the best exercise.
if CJ is the saftey to drop into the box to stop the run i hope he hits the weight room not sure how effective it would be dropping a 175 pound ex corner into the box compared to cooper, harvey jackson or singleton who are all 200+ but if CJ's the best guy then play him
Definitely agree that it would help to get some mass added to him, he looks really skinny. But I think the dude at 175 packs the wallop of a guy 15-20 pounds more than him. He seems like a well-compressed ball of energy based on what coaches and players describe and the limited special teams action I've seen. The guy stonewalled a couple KR's/PR's this year and has showed so far, even with a limited sample size, that he is a sound tackler.
To your point, I do think that CJ at 175 would perform better as a safety that plays run-support in the box than Cooper, singleton, and harvey at 200+ (though to be fair, I haven't really seen much of Harvey or Singleton). I know that sounds pretty ridiculous saying a 175lb DB being better in run-support than a 200lb guy in any other circumstance, but that's really how high I think of CJ. I'm drinking the kool-aid big time on this guy and I've seen enough flashes of elite ability to conclude that he looks on course to develop into an elite DB. And If CJ gets to the 190-200 range without losing speed, forget about it. He'll be a blackshirt for a while.
