I'll have to disagree with you on that. Click the link at the top of the page and see for yourself. It's around 7:20 on the link. Hartline has to slow up to make the catch and the DB breaks up the pass.
Looks like Hartline was 2 yards behind defender but had to wait on ball which was broken up when defender caught up.
The pass was launched at the 36 and landed on the 10. Only 54 yards in the air when it should have been about 60 to be completed clean.
I agree with you. This was under thrown once again by RT17
