Sentry??

It's no secret that i'm an IronMan fan. I'll read anything with the golden avenger in it which brings me up to my point. The other day i bought Ironman Vol.4 #9. At the end Nick fury sends a new avenger after him named "The Sentry". After seeing this i looked up the sentry on the ole Interweb and i found a picture. This picture looks almost identical to Captain Marvel. So i loked up Captain Marvel. Nethier metions the other, so can any one tell me if this is a lack of creativity from marvel or if thier is a bond between Captain Marvel and The Sentry.
