I think the thing we need to realize as fans watching the college season and now the combine; the scouts and GM's of NFL teams already know the players and where they are slated to be drafted. This also goes for mock draft sites. For example, Aldon Smith was ranked as a 10-15 pick and was considered a reach at #7. I doubt that the scouts and Baalke thought this kid had a good enough combine to take him at #7, they decided this about 95% based on his play on the field that year. They used the Combine to validate their scouting.
The same should be said about Stephen Hill. The scouts know his skill and know where he should be taken, the Combine should further validate their choice to draft him #30 if that's where they have him rated. But, we as fans do not really know.
It would not surprise me if Hill gets drafted in the first round or the 3rd round. We simply do not know.
That being said, I am going to go and look at some more plays of Hill. As a fan, all I can do is watch You Tube videos and compare his play to other successful WR's in the NFL.
But one thing is for sure, there are a lot of good, big, and fast WR's in the draft this year. The 49ers WILL draft one. Which round doesn't matter, we are going to get one, and I am excited about that!
