This may seem odd to many of you, but Salmon didn't really follow the sport too closely before he decided to give it a try. Around the time he first began MMA training, he was called up by Rex Holman to help him as a training partner. Sean was interested and Rex figured that he'd make a relatively smooth transition to MMA. Now days, Salmon catches most of the PPV UFCs and the live shows on Spike but I'd wager to say that he hasn't seen much, if any, of the Kerr/Coleman era UFC events.
A lot of you would be surprised at how many of your upper level fighters never study tape of their opponents. They may have seen a fight or two of their opponent but don't do extensive scouting the way you'd think. Of course this doesn't apply to everyone but there are quite a few guys out there who believe that having a strict gameplan is more of a detriment than a help... especially if things don't go according to plan. Another reason for not scouting an opponent is that sometimes it causes a fighter to alter his style for a particular fight. While that does sound preferable at first, it can be a problem if you get away from what you already do well. A good example is the first time Tito fought Chuck. Tito knew he'd have a hard time taking Chuck down so he instead chose to stand up and trade punches. He abandoned his strong points (TD's, ground control/striking) thinking that he'd be able to surprise Chuck on the feet. We all saw how it turned out. If he'd have been able to take Chuck down and keep him there then it may have turned out much differently.
As for not learning anything from Coleman/Kerr/Lindland... I'd only really agree with Lindland. Coleman never really evolved his game much from when he began. He's picked things up here and there but not enough to really keep up with the top guys. The big thing with Kerr was that he was willing to expand his game. His open-mindedness was what set him apart from Coleman. Lindland is really the one who's evolved the most from when he started but, as it turns out, he's not a guy whom Salmon would probably emulate for a few reasons. Lindland comes from a greco background, Sean does not. Lindland has a completely different body type than Salmon. At this point in his carreer, Lindland has become much more comfortable standing up and striking... Sean isn't there quite yet. He will be eventually, but right now his wrestling and submission game are his strongest points.
