This is what happens when you have Tyrod Taylor as your QB. You have no idea that you have an excellent WR in Woods on your team because TT buried his talent. At the time 8+ million seemed high because you can't be sure what he is - because of the QB. Robert does miss a good bit of time though.
Watkins - no - he's not the kind of guy you pay huge dollars to. Hence he's not been signed to a long term deal.
Try not to live in the past though, seriously. It does absolutely no good. We have to build weapons around Allen and we're going to need some good fortune and Antonio Brown type in the 6th would be nice, haha. They got so damn lucky.
