Well...umm....uh....but they were mega superstar five star recruits! Sefo isn't. So there!!
Listen, I'm sure there are many. But I'd be willing to bet there are many more that improved as they matured.
My only point is that some guys just seem to have it in them to throw lots of interceptions, even guys who have all the tools, and even guys on good teams. For sure, that doesn't mean Sefo is one of them, but it doesn't mean he's not either. Time will tell. And yes, it's probably true most guys throw fewer pics as they progress from year one to year four.
Look at Simms agaisnt CU in the 2001 championship game. Simms was a damn fine player and one of the best qb's of all time at that school, but he had to be really good to overcome his relentless tendency to throw interceptions at the worst times. Those pics were absolute momentum killers for his team and you could count on him doing it.
