I think one thing we can all agree on is that we're down on Danny Amendola's 2013 performance, but I'm not quite as sure that one year of seeing Edelman receive 151 total targets equates to him suddenly being a man of steel who's definitely better. It would seem to me that whoever is going to receive the targets like that is going to put up the numbers. Just for comparison:
Edelman--105 catches on 151 targets (69% completion rate) 54 first downs 10.1 yards per catch
vs
Amendola--54 catches on 83 targets (65% completion rate) 37 first downs 11.7 yards per catch
This tells me that if Amendola had been the one receiving 151 targets, he'd have numbers that were not only just as good as Edelman, but in same ways even better. He basically put up equal numbers when you take the 1/2 target aspect into account.
Much like last year, I would prefer to keep our previous slot guy, but I won't be losing sleep over seeing Amendola take over either, especially if another sense of the WR weakness is addessed with a player of equal or better talent. This would include guys such as Sanders, Maclin, Nicks, etc. It would also include lesser costing possession receivers like Cotchery as well. Only Belichick knows how the money should be spent at the position, and whether or not Edelman is worth the kind of money that he may command on the open market.
