I started a study of all CB's drafted between the years 1990-2005. To make things as simple on myself as possible I split them up into divisions. I started with the NFCN. I've only got 4 rounds done so far. I wanted to post what I had found so far to give myself a sense of accomplishment and to see what you guys thought. I do not have the data compiled because I just want to post that when I'm done.. but trust me it is there. These numbers are the average career numbers of a CB coming out of the NFCN in rounds 1-4 through the years 1990-2005. In round one I found: The Packers drafted 4 CBs. The Vikings drafted 1 CB. The Bears drafted 1 CB. The Lions drafted 2 CBs. These clubs spent a total of 8 picks in the first round on CBs. The average numbers for those players were: 5'11'' tall 191 lbs appeared in 114 games started 87 games made 315 tackles picked off 19 passes defended 24 passes more misses the pro bowl than made it (1 player out of 8 made it one time) the CB's were drafted around the 17th overall position in the round and played 8.5 active seasons. In the second round The Packers, Vikings & Bears all picked 1 CB The Lions picked 2. The average numbers for 5 CBs picked in the second round are: 5'11'' tall 196 lbs appeared in 89 games started 71 games made 308 tackles picked off 14 passes defended 24 passes more misses the pro bowl than made it (1 player out of 5 made it one time) the CB's were drafted around the 45th overall position in the round and played 5.7 active seasons. In the third round The Packers & Vikings picked 3 CBs The Bears & Lions Picked 2 CBs. The average numbers for the 10 CBs picked in the third round are: 5'11'' tall 192 lbs appeared in 59 games started 38 games made 145.5 tackles picked off 7 passes defended 18 passes no one made the pro bowl. the CB's were drafted around the 45th overall position in the round and played 5.5 active seasons. In the 4th round the The Packers picked 1 CB The Vikings picked 4 CBs The Bears picked 2 CBs The Lions picked 3 CBs for a total of 10 CBs picked in the fourth. The average numbers are 5'10'' 189lbs appeared in 60 games started 23 games made 103 tackles picked off 6 passes defended 17 passes 1 out of 10 made the pro bowl they were drafted around 123 overall and played 4.4 active seasons. You can see that as the rounds go on not only do the CB's get smaller in both size and weight (minus the slight upswing on round 2) on average they appear in and start in less games. As a side effect from that the rest of their stats decrease as well. The passes defensed stay pretty even. The drop from the 2nd to the 3rd round is the worst as far as PD's go.
Well, the way Ireland does things is different from the NFCN GM's look for Cb's, in fact if a Cb is not a certain height and weight they will remove them from their draft board.
I know that every GM is different. The avg CB for three rounds over 15 years in one division is 5'11''. Vontae Davis is 5'11''. And I would hope that he could get that many tackles. It wasn't really to scope out what our FO is doing; but more to see if (once I get further) that there is a league wide trend or a division trend. Right now it seems that the CBs coming out of the NFCN are 5'11'' and play at least 4 years worth of football on average.
Parcells is much like Ron Wolfe WRT modeling positions and not deviating from known successes... it is only on rare occassion that they will deviate from their script and take a supremely talented player whose 'measureables' do not conform to their bands of excellence.
