I would love it if Seattle looks at one of the four guys at the end of the first round:
Jace Amaro (TE/WR) Texas Tech 6'5" 260 lbs 106 rec, 1352 yds, 7 TDs
He was listed as a TE but he really is more of a hybrid wide receiver. He does a good job of using his size in traffic and is physical after the catch. In watching him he needs to refine his blocking quite a bit. Most consider him the 2nd best TE on the board so he may not last to pick 32.
Jordan Matthews (WR) Vanderbilt 6'3" 206 lbs 112 rec, 1477 yds, 7 TDs
Very impressed in the limited times I've seen him so far. Good combination of size and speed (listed as running a 4.5 which isn't bad for a guy that tall). Little bit of a slight frame, but can probably add 8-10 pounds onto that frame without losing speed or quickness.
Allen Robinson (WR) Penn State 6'3" 210 lbs 97 rec, 1432 yds, 6 TDs
Didn't watch him play much but I like what I've read about him. Maybe somebody else can give a little scouting report. But you can't ignore 174 catches for 2470 yards and 18 touchdowns over the last two seasons.
Kelvin Benjamin (WR) Florida State 6'5" 234 lbs 50 rec, 954 yds, 14 TDs
Easily the most physical of the four on this list. Very difficult to bring down (reference 19.1 yds/catch). He is also the most raw in my opinion. However he also may have the most upside of any receiver in this draft (not my words). Seen him going anywhere from a top 10 selection to middle of the second round.
I really think a bigger target that is a real quality pass catcher is what this offense need to go to the next level. I realize that we also need to address the offensive line (maybe even more than getting another pass catcher) but all of these guys will be gone by the 64th pick for sure and we can probably still get an OG or RT at that spot.
