Criticizing Sammy for being injury prone but not OBJ is just lying to yourself.
Mkay....might want to slow your roll a bit there.
(As an aside, IMHO, when it comes to injuries, I don't think the word "criticize" is quite the right word, regardless).
I was mainly taking exception to your assumption that "OBJ plays only 12 games a year."
[Hypothetically, consider a four year player that plays all 16 games his first three years and then misses all 16 games in his fourth. It would be misleading to say this player "averages 12 games per year." Even though 16 games were missed, spreading them out over four seasons implies that the player has chronic, recurring injuries-- rather than one major one.]
Admittedly, I don't follow OBJ that much. But a quick glance on the ol' internets shows me the following:
Freshman year at LSU: played full season
Sophomore year at LSU: played full season
Junior Year at LSU: played full season
Rookie year NYG: missed first four games with hamstring injury, then played next 12 (and had 91 catches for 1305 yards in just 12 games!)
Soph year NYG: healthy for all 16 games (missed one game due to disciplinary action.) 96 catches for 1450.
2016 year NYG: played all 16 games. 101 catches for 1367.
2017 year NYG: ankle injury, missed 12 games.
To me, if you look at the last seven years, OBJ was mostly healthy for six of the last seven years.
There are plenty of reasons personality-wise to be wary of OBJ. But as regards injury concerns, I think the main issue is to determine how his ankle has recovered from surgery. Prior to the ankle, OBJ has proven to be remarkably durable.
