cbssports.com = Frequently updated Rankings, prospect info, see players by position as well as overall, - keep in mind you can click on a HEADER - ie: player name - (to sort database alphabetically), or Height/weight/40-yd time, etc to arrange players by those factors. This, and drafttek.com are my go to rating sites.
cfbstats.com = A go to site for FBS stats on most players. Click HEADER for "players", select & click on a players "team", scroll down team site where players are listed alphabetically, click on player name & see 2015 stats, for previous years click HEADER for 2014, 2013, etc. ------->NOTE: This site gives you the ability to find player stats with just a few clicks, all you need is player name and team. Additionally on this site, you can click on HEADER "National", and you will see offensive & defensive player stats arranged by FBS National leaders. Great site, use it all the time.
mockdraftable.com = Post combine, complete info. by position & by year. The graphs that this site produces can go a long way toward understanding specific physical aspects for each player compared to all others at the same position. You can look at the specific metrics that the Seahawks desire, for example, just look at Frank Clark, Tyler Lockett's #'s and graphs from the 2015 draft, you'll see what the Seahawks saw pre-draft as I did, I had both on my 2015 Seahawk draft mock for good reason. This is an excellent site.
