These comparisons really don't work at all.
Niels Laros is not a front-runner type like Timothy Cheruiyot and it's doubtful that Tim was really as young as Laros when he burst onto the scene. Laros is really talented at the 800m at his age, but he is still about 1.6 seconds slower in the 800m than Tim and he may not get to 1:43 low, as he is also pretty good at 3k/5k, which Tim has had no success at to this point.
Cole Hocker is no Matt Centrowitz, nor Matt Cole. Matt won outdoor medals starting his junior year in college not because he had an explosive kick in slow races but because he was a master at positioning, like Bernard Lagat, always in perfect position in slow races to go with the leaders, never a mistake until late in his career. He was smooth, never showing effort even at 50 second pace in his 3:50 Olympic gold. Cole is all over the place in his form, which is not smooth at all. He is an explosive kicker in slow races, making everything happen from the back usually in the last 100-150m, not too dissimilar from Beamish who has even better acceleration. Historically, he would not be perfectly positioned but would be boxed. He did much better at World Indoor but was still boxed until late and was very patient and left the box when he got the chance. He is already close in time, with super shoes, to Centro's best time, but will likely go a lot faster and be more competitive in fast races.
Finally, Hobbs Kessler may be in Nick Willis's old group, but he is not very much like Nick Willis. Kessler has already done a front-run to a World indoor medal. Nick Willis would never lead or almost never, stay in excellent position drafting, and then clean up the lesser medals and places at the end in his best races (against multiple dopers). He was a good 800m runner for this generation of 1500m runners but he never had the kind of speed that Hobbs has. Hobbs closed a Michigan in 50 and he will be a better 800m runner than Nick. He will also get a lot more out of his potential at 3k and maybe 5k than Nick did, despite his high mileage. The mileage is another major difference between them. Hobbs is not yet comfortable with high mileage, while Nick ran many 100-120 mile weeks and he did regular long runs that were nearly twice the length of Hobbs' longest current run.
