It wouldn't surprise me that if 2008 is less than spectacular, his time here will be shorter than expected. |
JLC's point is that by giving him big up front money and guaranteeing his salaries in 2008-2009, and a good portion in 2010, the scenario you suggest is not a possibility.
The point is not that Portis is a flash in the pan running back, but rather that running backs typically have short windows of effectiveness in the NFL. Portis has a lot of carries in his first five seasons, is not a particularly big back, and his game is extremely physical. I think he can do it for another three years, but probably won't go much after he turns 30 - but few backs do. I suspect also that is part of the reason why the FO felt comfortable guaranteeing salaries basically until Portis is 29-30. That is typically when elite running backs decline in effectiveness (typically dramatically, see Shaun Alexander - Tiki Barber is an exception, but had fewer carries early in his career).
