Since discovering the existence of the cap your obcession with it has begun to warp your perception of value in team building. Cap space doesn't trump talent, it allows you to acquire or retain it. The Pat's actually want Asante to stay and play here - otherwise they would have goaded him into screaming louder sooner and traded "roughly zero" for that draft pick prior to the 2007 draft. They have offered him a long term deal that averages $6M per and therefore likely includes a double digit signing bonus well in excess of $7.8M, which means they do not share your cap value/holdout induced view of him as a $2M player. Nor do they covet that potential $10M cumulative draft value down the road more than the substantially greater than zero value of having playmaking talent and stability in their backfield for the upcoming season, not to mention the next 4-5 seasons.
If they end up trading him for a 1st in the 2008 draft it will not be a big win, but rather having made the best of an unfortunately unworkable situation. Same as with Deion, whom they also actually would have much preferred to retain long term. We may or may not be better off without him going forward talent and cap wise, having already traded out of the first with our second pick in the round this season because having 2 first rounders in a shallow draft didn't represent substantial value. And we certainly weren't better off without him in 2006, and will apparently be paying someone (or ones) the money he rejected to cover the position in 2007. We saved substantial cap space going forward last season by replacing an unsignable Branch and Givens with Caldwell and Gaffney et al, but it cost us in offensive production/efficiency and wins. We have been unable or unwilling to replace that via the draft, so we have now begun trading draft picks for veteran WR and paying them as much or more in cap than Branch and Givens would have cost to remedy that deficiency in 2007 and potentially beyond.
Championships aren't won on paper, solman, and the only real value of cap space or draft picks is measured in the talent it enables you to field being sufficient to meet your goals in the present as well as the future. If we enter the 2008 offseason with tons of adjusted cap space and 3 first round picks and no ring, Belioli will not consider that a big win but rather a crashing disappointment. Because they will have squandered another season in Brady's prime - not to mention potentially the final season of impact players like Harrison's and Bruschi's and Brown's and Seau's careers.
I think they will figure out a way around this with or without Asante. But I'm not going to kid myself by trying to rationalize how this was their plan all along. Anything short of signing him to a reasonable deal long term is just some variation of plan B.
