Nicks EXCELS at being physical and beating tight coverage of grabby DBs in man schemes. Just think about how much experience the DBs will gain having to practice against that receiving corps (and that's not just me saying that, heck Vontae Davis feels the same way). Just having him on the field immediately requires the secondary to change there coverage, and provide help over top. They know that if you don't, he has a very real chance of beating his man for a rather large gain. By drawing all that attention, he relieves the pressure and opens up space for both TY and Reggie. For proof, take a moment and think about where our offense was prior to having Da'Rick Rogers on the field. Once Reggie went down, TY had immense trouble getting open because DBs got physical with him because they knew they had help overhead. Once Da'Rick started playing, they knew they had to respect the other WR and this, in turn, loosened up the coverage for TY.
Now add what Rogers was able to provide just by being on the field during his short time with the team, to a receiver who has a documented history of blowing up tight man coverages, and catching balls reliably. What you get is a secondary that has to devote more resources to preventing Nicks from breaking loose, which opens up the field for everyone else. The pass packages, hell, the play-action alone would do quite a bit to revive our run offense. Teams could no longer to send an extra db to help kill runs.
This also does more for Luck than many realize. think about how many times Luck has over or underthrown a ball by just a hair (Reggie Wayne's knees don't appreciate this). I can't count how many times he'd have Hilton open and just get it slightly over his head.With Nicks we get a player who is great at adjusting to the ball...some of the throws that man catches are insane. Couple that with his motivation for not only playing with a great, young team...but also having the chance to make a mark this year for a great free agency next year, and you have the makings for a damn good year. With Nicks, I am not looking for a homerun WR (although that would be nice), what I would be perfectly happy with is a player who has the consistency that he has...even in "down" years. I know it was mentioned earlier, but reliable 3rd down WRs are a huge part of offensive success - one that we sorely missed last year after losing Reggie.
This is one of the moves that has me very excited for this coming season. I would not be surprised if this leads to Nicks, Wayne, and Hilton having 1,000 yd or near 1,000 yd seasons.
