I think most fans have progressed beyond the point where they obsess over dollar amounts. This team is in a position where 10 mil costs less than 5 mil for a team like the Cowboys. If he bombs out the team takes the hit and moves on.
The gamble is that hes getting better at the position and will produce at a higher level for the Phins. It is a gamble but one that a team like this should be taking. The frightening deal is the one handed out to Jones. Even if he plays at a high level its tough to justify that kind of outlay if there isn't a significant improvement in the defensive unit as a whole.
