You're overrating Wladimir at this stage in his career. Wladimir got dismantled by Sanders who was seen as a past it fringe contender. Wladimir tired himself out after 4 rounds vs Brewster and got himself stopped. And trying to hype up beating a 42 year old past it Mercer who had 6 fights in 6 years is not really relevant to this match up. This is a loseable fight for Wladimir much more than you're portraying. A prime Wladimir with Steward ? I'd make Wladimir a huge favourite. Not so much the version of Wladimir pre Steward.
