I said over the past 5 years.. You picked one year that happens to be 9 years ago which isn't even close to what I asked. I asked because I wanted to see consistency of the top 3 picks over multiple years all working out to be good players.
Fine.. lets look at the next few years for the Panthers then.. since this was your example..
2002 draft
1st. round 2002 Julius Peppers - yup, good pick, pro-bowl - win
2nd round 2002 DeShawn Foster - didn't play in 2002 and marginal impact after, released in 2008.. Bust
3rd round 2002 Will Witherspoon - started mid 2002 and has been a starter ever since - win
2003 draft
1st round 2003 Jordan Gross - instant starter and has ever since - win
2nd round 2003 Bruce Nelson - played two years and it out of the league from injuries - bust
3rd round 2003 Mike Seidman - Appeared in 12 games was 3rd on depth chart and it out of the league from injuries - bust
2004 draft
1st round 2004 Chris Gamble - instant starter -win
2nd round 2004 Keary Colbert - filled in as 2nd receiver first year.. never turned into an every down player and is no longer playing - bust
3rd round 2004 Travelle Wharton - started after 5 games and has been a starter since - win
So this is just 4 years vs 5.. don't have the time to keep going.. As you can see of the 4 years they had 8 wins and 4 busts.. The point is no team has been perfect in their drafts.. Players turn into busts for many reasons.. and it can't be predicted..
