I assume you are on a windup here. If not, then you must be the "feeble minded idiot" that you brand a huge number of Saints fans as.
Addressing, your first point, Downs is clearly not ready for the competitive and physical nature of the championship. His touch is poor, his positional sense is woeful. Any decent scout should have seen that he is not ready for this league, even as backup.
Point 2, we didn't need a CF who scores lots of goals. What we needed was a strong, physical target man who can hold the ball up, link the play and create space for goalscorers such as Armstrong and Archer. This is what Che Adams did so well for us. Anyone can see Downs is not that player.
Point 3, there are plenty of players that could have filled that role. Three teams that we have already played have shown this, Derby have bought Carlton Morris, Wrexham have bought Kieffer Moore, Hull have bought McBurnie.
These are all players that SR would never buy because they only buy players with a view to resale value, not who might just do a job for a season and get us promotion.
Point 4, it didn't require visionary skills to predict that someone| who has had a series of recurring injuries for two years, including hamstring, would breakdown again. Especially when, after not having many minutes this season we played him 3 times in 8 days.
I don't normally respond to other posters in this way, but your post riled me with it's idiocy. Congratulations, if that was your aim. Although, it does feel too easy taking aim at your points, rather like attacking a dead sheep
