I recall the last year that Carpenter was the full time starter at FS (back in 2002) there were at least 3 interceptions that I saw (and I only saw maybe 6-8 games that year) that he dropped.
He has terrible hands, and his dropped INT would have turned into a TD had he held onto the ball. He'll drop at least another 3-5 this year. He'll still probably get 3 or 4 this year, but I think that he's capable of doubling that.
That machine they use in training camp for WRs to work on their hands, they need to work Carpenter on one of those things for 2 hours each day of practice.
