Speaking just for myself, I consider Gregg rigid because he never really seems to have a Plan B. We all know Plan A, the opponents know it and can prepare for it, and it makes it easy to stall the US attack even with a massive talent gap. I think most USMNT fans would welcome a lineup that got a more creative playmaker like Gio in more goal dangerous positions more consistently. My concern is that once he builds the system, that’s all that GGG will try to do, even when teams put clamps on Gio and stop the US attack. He’s not rigid in the sense that he doesn’t change his system over time, he’s rigid because once he settles on a system he won’t change game-to-game or within a game to counter what the opponent is doing. He just makes like-for-like substitutions- I’m sorry “solutions”, a phrase I hate but it’s decently representative of why I dislike GGG as manager. Solutions are needed for problems, and calling substitutions “solutions” indicates the player being subbed off was the problem. The system often was the problem (yes, I’m aware that often times substitutes can be tactical changes, but that’s rarely the case with, it’s usually a RB for a RB or a 10 for a 10 etc). He needs a plan B.
Again, GGG has slowly changed his system over time. You just need to look at the early GGG games versus the World Cup to see that. And I liked the MMA midfield myself. It was solid, and it meant that Lletget was not on the field. But how many times does the US need to cycle the ball from right to left to right, cross the ball into Jesus frickin Ferreira- a player who I actually enjoy watching but heading home lofted crosses against international CBs isn’t his strong suit- before Gregg changes things up?
