I don't agree with this at all. Tallon had a number of ways to approach Florida's roster situation. However, it's important to understand something. Florida's had a tough time for the last several years. They haven't been competitive, and there isn't exactly an existing marquee lineup that makes the team attractive to free agents.
That being said, in order to secure decent talent, he was going to have to overpay. From a trade standpoint, he could have surely acquired other players at established, more reasonable contracts, but it likely would have come at the expense of some of the massive amounts of picks, and top tier prospects they've been stockpiling, and I'm sure that wasn't appealing. They now have a pretty decent stable of established, veteran NHL'ers who will be complimented and supplanted by the stable of young horses they have.
Tallon didn't overpay because he doesn't have a clue what players are worth. He overpaid because he DOES know what they're worth...and all other things being equal, who's going to take an identical pay day to go to Florida rather than another market? Florida had to up the ante on every contract it gave out, in either increased term, increased salary, or a combination of the two.
