all the salaries of those 1st round pro bowlers compared toe the salaries of the 2nd & 3rd rounders, the difference is much greater.
look at the 1st round vs the 2nd round of the '16 draft. sure the top half dozen guys are great, but then the comparisons start to get a little tougher. there are a number of really good players in that 2nd round that i think we can all agree are absolute bargains.
