Modrak is more than capable of building a team the right way (see Philly). Marv will be there to ensure the franchise is being ran the right way. People forget that Marv was a GM in his CFL days. I really like Modrak, some may say he disagreed with the way TD did things. If that's the case standing in TD's shadows will pay dividends for the Bills in the future.
Now one has to wonder is MM the coach for the Bills.
