Yes to the first, no to the second. I don't know why people are so down on Jyles. The last two years, he's been forced into offenses run by people who no longer have employment as coordinators (Baressi in Winnipeg, Elizondo in Toronto). I think he can be a good QB in this league in the right system, with quality receivers and a proper O-line. Does Toronto have the latter two things? Not really. We'll see how Milanovich adjusts.
But how do you explain losing Burke, Brady (offered the co-ordinator position), and Himebauch (although still unconfirmed) to lateral moves?
Losing Burke didn't seem to involve Trestman. Apparently, we offered him a contract, but he wanted to jump to a different team and do something different. I can't imagine Trestman would have micro-managed Burke anyway, given that Trestman's background is offense.
As for Brady and Himebauch, assuming the reports are even true (and Herb has also reported that we have offered Himebauch the vacant OC position here in Montreal), maybe Trestman's style is wearing on them, but that happens to any head coach after a few years. Also, maybe they just want to live in Toronto. Maybe Toronto is offering them salaries we can't match. Maybe they want to be part of something new from the ground up, instead of running a mature offense entering its fifth year under the same head coach. There are too many unknowns for me to want to jump to the conclusion that Trestman is somehow driving coaches away. As is typical of Herb, we never hear this stuff when the team is winning, but as soon as we encounter adversity, out come the innuendo, unnamed sources, and speculation.
