The question still remains what do you do with him...
1) Keep him on the 53 man roster?
2) Keep him on the 53 man roster, then IR him so he can come back later on in the season?
3) Simply IR him and try to hold onto him for next year? (which his agent could potentially protest that it's not an season ending injury)
4) IR/release him
Also has he played well enough to be one of the top 6 WRs? ... I'd say the top 3 are locked in, in Adams, Allison and MVS... and some other WRs have out shined St. Brown in preseason games, the question is what has he shown in practice, where Davis and Kumerow names have come up a lot more often in writers reports, and then there is Lazard and Shepherd which have flashed some talent and good ST work as well.
