Because I'm a dork like this, I've also watched the videos and calculated all of the stride rates of the Rebel probables already save for one, who looks like a no-hoper on paper anyways.
The four probables that I like in order;
American Anthem - 24 strides early, 26 strides late during an 8F race after running a Brisnet E1 pace of 108 and an E2 pace of 112 while being pressured and dueling with Gormley for most of the race. Little wasted motion with this guy. He has stride length, length maintenance, and stride frequency. Only small concern I may have is that race may have taken something out of Gormley, so it's possible here as well. Gormley was put into a tough position yesterday around the far turn, though, when he was between horses and had pressure from both sides. Not uncommon at all for the middle horse to concede first when caught in that position. American Anthem's training says he'll be just fine too.
Petrov - 26 strides early, 27.5 strides late during an 8.5F race after running an E1 of 98 and an E2 of 101. His race prior to that at 8F he took 26 strides early and 27 strides late after an E1 of 96 and an E2 of 99. In those races it was left to him to chase Uncontested on the lead, which is not likely to be the case this weekend. He also had to deal with One Timer right after putting away Uncontested in the last race. He didn't get a break. He can sit back and relax a little more in the Rebel I think. Decent stride length, very good length maintenance, and okay stride frequency. If American Anthem stubs his toe I think this guy could be the one to capitalize.
Lookin At Lee - 25.5 strides early in both of his races at 8.5F, and 26.5/27 late after running very similar E1's and E2's of 75 and 90 in both. Good stride length and length maintenance, although average at best stride frequency. He's more plodder than a closer with a quick turn of foot, but he'll be running late once again and passing tired horses. Not likely to win, but has a good chance to finish in the trifecta and possibly grab 2nd.
Silver Dust - 26 strides early, 27.5/28 in his races at 8F and 8.5F. His last race he ran an E1 of 90 and an E2 of 91, which would actually make him fit the E2 lung opener angle as it was his first race back off a layoff (had ran E2's of 76 and 80 before that). He also looked like he gained about 5 lengths on the backstretch in his last race before leveling off late to some extent. Still kept to running though, and was able to finish 4th in the Southwest. He still runs a little green, but should improve this next race and could fill out a trifecta at a big price. Maybe even an exacta if the race falls apart late.
The four I don't like and who are all going to be bet to some extent;
Uncontested - 24 strides early in each of his last two races with a stride rate of 26 late in his race at 8F and at least 27 in his last race at 8.5F (counted the 7-8F portion because he fell back). He had E1's of 99 & 100 in those races and E2's of 102 & 104, but both times he sat unpressured on the lead so he was able to relax even though he was moving at a pretty good clip. He's got a lot of length to his stride, but runs ugly while doing so. There's a whole lot of moving parts to him that do nothing but waste energy in a horse. He also runs kinda stiff legged. Might be dangerous with an easy lead in the Rebel, but like his last race, I don't think he sees the wire near the front.
Royal Mo - 24.5 strides early, 27 strides late in a 8.5F race after running an E1 of 89 and an E2 of 95 while recieving little pressure from other horses. Very good stride length, but poor stride length maintenance and was really struggling at the end of the Bob Lewis even though he won. He loses that race if anybody even half decent showed up for it. He also doesn't much in the way of stride frequency compared to the other long striding types in this field. I would expect the early pace of the Rebel will be faster than this guy's last race, and I don't think he'll be able to keep up in the late going as they hit the turn. Don't like this guy at all.
Untrapped - 25.5 strides early, 28 strides late in a race at 8.5F after running an E1 pace of 76 and an E2 pace of 82. Shows good stride strength early, but poor length maintenance, and I think the fact that he was able to come along and finish 2nd in the Risen Star says more about the competition than him. Might grab a piece if there's a hot pace battle up front, but others of this type look more appealing.
Malagacy - 27 strides early and 30 strides late in a 6.5F race last time out after running an E1 of 100 and E2 of 108. Might have been slowed by a half a stride or so near the line because he was well in front, but no more than that. Will get his share of support due to being a Pletcher trainee who popped a 95 BSF in that last race of his, which is a BSF right in line with what some of these others have gotten (American Anthem, Uncontested, Petrov, Royal Mo are all mid 90's). Has the quick short stride of a sprinter and nothing more.
