For whatever reason, we remember Lloyd as being better than he really was. He was actually a pretty average kicker and a below average punter. Might have something to do with the Wisconsin kick?
As for the statement that field goal kickers don't seem to be as good now days, I compared kickers from this year to 2000. Field goal success is at 73.5% this year compared to 69.5% in 2000. Teams also attempt 1.63 field goals per game compared to 1.49 in 2000. I would say the difference in field goal percentage might have something to do with more turf fields now days. Because of that, I would say they're pretty much the same.
I tried to look back further, but this is what the stats for 1990 look like on ncaa.org:

Seriously, they can't have an intern enter that into a database or something?
