I agree about his stats, but stats can lie. Why would you throw in the direction of a guy that talented? Sometimes your stats are horrible, due to no one challenging you. He does have some limitations in coverage, but he's there to challenge the WR's and TE's, not stay in their back pocket. He's no Ed Reid or Palamalu, but he's not Roy Williams Either! Can you imagine bringing him in the box on run situations also? My oh my....the packages that can be run!
You could say the same about Sean Taylor. He was obviously a huge ballhawk going into his junior (and final) year with the Hurricanes when he was in college. Why would you think about throwing at him? He still managed 10 interceptions that season, and made much, much more plays than Mays did this year, or in any year. Same goes for Ed Reed, he was a huge ballhawk throughout his college career, but still managed to get the picks year in and year out. And he does it in the NFL pretty much EVERY year.
I think INT stats lie, to an extent. You either get them or you don't. It's not like a touchdown where you have to have your whole offense on the same page. An INT is just a guy using instincts to be where the ball will be and having the ability to come down with it.
I just don't think Mays is a ballhawk. I see him being like John Lynch as you, pittbull3, said in the OP. John Lynch is probably the best comparison I have seen of him yet.
If you want a run stopping enforcer who closes on the ballcarrier extremely fast than Mays is what you want. I'm not sure he is the ballhawk we are all looking for.
