MikeT always used to say there is nothing to this but I think he just didn't want to be proven wrong. Look at Irv's stats before going down with the injury.
Lifetime WHIP of 1, ERA hovering around 2, didn't lose a single game in season 11 and then has an ERA near 3.5 with a WHIP of 1.16 before he goes down with an injury. Its telling.
Same with a guy on my squad.
I thought I had spent too much money and got a lemon in
Furio Zeigler. Look at his game log for this season up until December 6th. The stats are dreadful. Then look at his stats from January 3rd till now. (keep in mind he never fully recovered from his injury).
I honestly think the game gives you warning when a player is going to go down with an injury. Especially pitchers. They do not pitch up to their ability at all.
