Reason for concern after 2 weeks? Pretty pedestrian tackle numbers so far. Been on the field alot, but they seem to be playing him pretty deep off the line of scrimmage. Hold for another week or chase after Dugger, Cisco or D Elliott who happen to be available due to other manages panicking and chasing offensive players on waivers.
I haven't seen Week 2 usage yet, but in Week 1 he was actually up near the line of scrimmage over 60% of the time and only played deep less than 30%. This is in line with how Flores typically uses his strong safety. Things seemed to change a little in Week 2 but Smith has been one of the most consistent DBs in the league the last several years, so I have faith he will finish where he typically does when all is said and done. All it takes is one big game to get him back on track.
