Personally, I think Webb could be a steal. As a late pick, why not take a flyer on him? I may be a bit biased as I am a Bulldogs fan but I have watched him a lot (of the limited games he played). Unfortunately he has has some injury problems over the last year and a half which kept him off ice. One was a broken collar bone, which one repaired, is supposed to be stronger than a regular healthy one (same injury as Kane and McDavid).
Basically he's a good defender with offensive upside. He's certainly not afraid to use his body and play a physical game. Once he returned later in the season, he immediately improved Hamilton's blue line and didn't look like an OHL rookie who missed a year and a half. Seeing him get drafted was a surprise to me but I also thought it was smart of Detroit to get a half-step on the rest of the league and have his rights in case he really breaks out next year. Well worth a low risk 6th round pick.
