I'd be intrigued by an attempt to sign WR Andre Holmes from the Raiders with a short money contract, kind of like the Emmanuel Sanders one year offer. He's a guy who the Raiders seem to undervalue despite having some games with good production and some pretty appetizing athletic skills. He compares favorably to Dobson in a lot of measurables (I know, I know). Dobson on the left, Holmes on the right:
Height: 6'3", 6'4"
Weight: 210, 210
40y dash: 4.37-4.44, 4.53
20y shuttle: 4.33, 4.31
3 cone: 7.19, 6.69
Vertical: 35", 35"
Broad Jump: 10'1", 10'10"
In limited opportunities, he has definitely shown an ability to use his size and athleticism to bring down contested catches, and has had some big play ability (19 of his 72 catches have been 20+ yarders and he has averaged 14.7 and 17.2 YPC over the last two years). If he can be had for cheap, I'd like to see what he could do in our offense.
Edit: Of course I failed to mention he was undrafted, the Raiders tendered him at the lowest level, and no compensation would be due Oakland if the Patriots signed him.
