A little perspective.
Hopefully everyone on this board understands the cumulative effect of training. Its not just what an athlete does this week or even this month that determines fitness; its what he has done in the last twelve months. If I run 30M/wk for 51 weeks then run 100M/wk, I can say I'm running 100M/wk. But am I as fit as someone that has been running 100M/wk for the other 51 weeks? Of course not. Given that consider Webbs last 12 months.
A year ago he was just coming off an Achilles injury and in the pool. He was in a differen system to boot. He runs a mediocre (for him) outdoor, then bags it, goes pro and takes the summer off (by the accounts I have seen). He then starts back up from scratch this fall. Even with that, he still runs an indoor mile PR.
Look, I'm not praising or bashing him or the way he trains. I'm just looking at the big picture, and this isn't someone I would expect to be tearing up the track right now. My prediction is that he improves this summer, maybe runs some "B" races in Europe (at least he said he was going), maybe PR's, maybe doesn't, but works on getting consistent and getting experience. I don't pick him to make the Worlds team, but I'll hardly be stunned if he does. However, come September, he is going to be light years ahead of where he was this past September, and next year is the year I would expect to see him begin to flirt with a huge breakthrough.
One final thought. The most reliable indicator of talent is the RATE of improvement. Ryun went from a non-runner to sub-four in, what two years or so? Shortly after Webb ran 3:53, I had chance to ask Steve Scott how long it was from the time he ran 4:06 (Webb's soph time) until he ran 3:53. Two years, he said. That's the same improvement rate as Webb. I don't know if he'll ever run 3:47 or never PR again, but I'm not going to get carried away one way or the other with what he does this year.
