I personally don't think Bader get's the respect he deserves. I understand that he has a two loses via KO and two via sub - one from past prime Ortiz but anyone can get caught for real, respect to Mr Ortiz though.
When he lost to Glover, Glover was on a 19 fight win-streak and Bader honestly almost put him out more than once. Bader went in for the kill and got sloppy, he had a tendency to over-commit a little too much - rest is displayed in the GIF below but I genuinely would pick Bader to beat Glover at this point. I'm in the minority and I expect the obvious comments to come in but I'd lay money on Bader, he's fighting much smarter and more calculated these days. He knows his strengths and weaknesses well now.
He beat #6 LHW and KO artist OSP, easily via UD. It wasn't the most exciting fight but it was a dominant win over a dangerous guy and followed that up with a victory over the notoriously elusive and powerful wrestler, Phil Davis that was cut due to politics rather than his ability to compete in MMA.
And of course he topped off his 5 fight win-streak with a win over former champion Rashad Evans in a fight many counted him out of. Bader walked through Rashad. Bader ended his streak beating 3 top 10 guys consecutively.
Since the loss to Glover, Bader has beaten all of his opponents with fair ease and hasn't been in any adverse situations due to him fighting well. He is fighting to his strengths, he has great cardio, great power and great wrestling. His boxing and kicking game have come forward leaps and bounds imo and I believe he is a real threat to Rumble Johnson, this fight is no gimmie match-up for Rumble.
