We should not be satisfied with just cutting X and Mevis and firing Ventrone (and yes, he should be fired, at this point). If we could trade Ethan Evans for a future seventh, I'd do it in a heartbeat.
Evans has a huge leg, but he's also constantly and consistently outkicked our punt coverage because his hangtime is well below-average. It's responsible for the big returns we've seen. He's been very inconsistent as a punter. The Seattle punt was the best punt I've ever seen, but he's not even close to Hekker when it comes to consistently placing the ball inside the twenty/ten. As a kickoff specialist, he's had tons of touchbacks. That just can't happen in the NFL in this day and age, and it's affected his punting as well when he's done it.
Personally, I've seen enough of him. He hasn't improved at all in the four years he's been here, and it's part of why our punt coverage has been so terrible. Maybe a new special teams coach could help him with it, but personally, I've really seen enough of him to think - in my honest opinion - that he's also part of the problem.
EDIT: Honestly, Joe Cardona and Grant Stuard have been the only regular special teams players doing well. Everyone else gets a D- at best.
