Let's put it this way, I started the last Colts thread.
That said, when the Jets suck, their fans will live their football lives vicariously through the Colts.
IMO, the only important thing to be concerned about is the health of the pass rush unit. To illustrate my point, I'll refer to last year's Pats/Colts game. When Freeney and Mathis were getting to Brady, the Colts were winning and the Pats offense was struggling. However, F&M had played the entire game and by the 4thQ, they were worn down. That resulted in Brady getting more time and the Pats offense exploded for 2 late TDs.
Now, Freeney is recovering from a serious foot injury. The good news is I really like their 5th round pick, Marcus Howard (DE, Georgia). He was a late starter in his college career and has upside. He seems to be cut from the same cloth as Mathis. If Howard can play well enough to be a contributing part of a 3-man DE rotation, this pick will have the greatest impact from the 2008 Draft. When Indy won in 2006, IMO, it was their terrific Pass Defense that made the difference. That said, if Howard struggles and Freeney is slow in returning, your team is toast.
Note that I don't mention anything about Peyton or WRs. They'll get their points, but Indy will only go as far as their D takes them.
Welcome!
