Great post Nitsuj,
I'm going to write an article later on the risk/reward of going for 2, especially in bad weather, but I agree I'd like to see him go for 2 more often as well.
As far as a script, I think Haley runs an open script as opposed to Andy Reid who always ran a set script, and ran those plays in order. With an open script, Haley is checking to see how the D reacts to those plays, so hopefully, they can be taken advantage of in the same personnel groupings later. I have to think this strategy is currently working since the Steelers are scoring more at the end of halves and games, when they need to. I am with you though, I would absolutely prefer Ben to call all of his own plays at this point in his career. Haley than can advise on the sideline, what he sees, and how they can take advantage of it. It seems to me that it would be Haley's decision about the script, but if it wasn't working, I'm sure Tomlin could advise otherwise.
Can't argue about the Pats, until the Steelers win there.
Though it is an insane number of road game losses to losing teams, and that jumps off the page. I think he's 8-14 now, and the odd thing is he should be a terrible coach at winning games. The crazier thing, is even with this bad tendency, he has a chance to break Don Shula's win record for first 11 seasons, this year. This means Tomlin is very good against good to great teams. He does seem to have his teams ready when they play great teams, and his total record has shown that he is extremely successful against better talent. If he cleans up the road losses to losing teams, he will be an even better coach, though he has been getting better at it the last few seasons.
