Historically, the Panthers have not drafted well with WR. Other than #89, and #87....the Panthers really have not had much success drafting WR. And #89 was drafted in the 3rd as a PR/KR not as a WR by Seifart. I don't think the Panthers had a clue what they were getting with that 3rd round pick.
It's not like they have not tried to correct the WR situation...they have just been very bad at it.
They drafted Colbert 2(62) in 2004, Jarrett 2 (45) in 2007, Robinson 4 (118) in 2007, and all were busts. And then they tried again in 2010 with LaFell 3 (78), Edwards 3 (89), and Gettis 6 (198) with only limited success as a whole group. They gave it a half-hearted try again in 2011 with Pilares 5 (132), and 2012 with Adams 4 (104). Other than LaFell (with only limited success) nobody has really done anything at this point. The jury is still out on Adams, Gettis, and Pilares but I would say this is the make or break year for those guys. Someone needs to step up this year if they want to be in the NFL next year.
