Doug Wilson let go of two of his top four last year and tried to warn you of the consequences of that act.
Also Doug Wilson is not a green lantern who can just will defensive depth into existence. Plus I still think Burns is a large part of the problem and I wouldn't call him depth.
Yes, but warning "we're gonna suck" doesn't make it ok and doesn't mean it's the right thing to do.
Wilson has brought this on himself. He has plenty of underutilized assets he could move to address the defensive depth. He also would have plenty of cap space to address defensive depth if he hadn't blown it on wasted space like Burish, TK, and Brown or wasted roster spots like Scott. But that brings us to the second DW shortcoming, that he's just as terrible at acquiring defensive depth as he is forward depth, often overpaying for dead weight. I don't even need to list all the terrible contracts and acquisitions we've done for defensemen and the assets we've given up for them.
It's not all on DW, but the team has 2 NHL defense-first defensemen right now (MEV, JB) and 1 guy who hasn't played D in years (Burns), a guy who might never figure it out (JD), a guy who's learning and is in the NHL due to team need (MM), and AHL caliber players (MI, SH). Seeing Burns score so many goals from the blue-line highlights how lacking the blue-line offensive talent has been recently.
This team may turn a corner once they get a homestand going. But if the blue-line isn't fixed in addition to TM/The Players figuring out exactly how to succeed together it may be the end of the DW/TM era.
