University of Florida wide receiver Percy Harvin is drawing heavy scrutiny for his multiple character issues, including testing positive for marijuana at the NFL Scouting Combine along with a history of clashing with teammates and coaches. What has gone largely ignored are Harvin’s durability and medical concerns that may concern NFL decision-makers as much as his behavior, according to Rich Cimini of the New York Daily News. Per the report, Harvin needs to have a surgery to repair a “hole” in his foot bone and he’s already gone under the knife several times in the past to address ankle and foot problems. “Oh, yeah, he’s got a bad attitude and tested positive for marijuana at the scouting combine, my sources confirmed,” Cimini writes. “Other than that, he’s a Boy Scout.” We’ve heard separately from a league source that Harvin’s medical background is raising eyebrows around the league. Despite his character red flags and medical issues, though, Harvin has a ton of talent and someone will be willing to take the risk.
