The reports should be taken with a pinch of salt... there is no doubt that it's all coming from Meehan/Newport.
However, it's not like it's all new information. We knew back in October that there were no talks between the sides over the summer and that the first meeting was at the start of October when the Blues went to Toronto on a road trip. So it's a safe assumption that Armstrong was dealing with the likes of Faulk and Schenn before looking at Pietrangelo. Immidiately after those talks, Armstrong was in the media saying how we have wealthy players, but no really rich players and that's the model we see to have continuing success. So his position on the ask is pretty clear, it's just whether we believe the ask was $9m and the Blues wouldn't go above $8m.
Meehan/Newport will know that there is little benefit to drag the negotiations out over the season. When a player is as established as Pietrangelo and looking for a long term contract? One outstanding season isn't going to significantly change the AAV. One significant injury absolutely could. Unless a top player wants to test UFA, or is genuinely undecided, then getting the security of the deal done early is a benefit that they typically want.
Edit: Also, talking about players liking security... let's not forget how much of an advantage we still have with the ability to offer the eighth year.
Eight years at $8.5m is a $68m contract that he knows he's getting. It's going to take a cap hit of over $9.7m for anyone else to be able to offer him a $68m contract. Even if it is $8.25m, that's still going to be almost $9.5m AAV for anyone to match the total dollars of the contract.
While the insiders are out there talking about teams looking to cut payroll and things like that, the teams that are going to be largely immune to that are the larger markets. Those markets tend to have higher taxes as well.
