Heh, it looks like you were inspired by the same "favorite players" thread as me. I made a very similar team the other day, completely of guys I had never seen online.
DE Gino Marchetti
DT Keith Millard
DE Rulon Jones
MLB Nick Buoniconti
SS Dick Anderson
QB Bubby Brister
WR Eric Martin
WR Yancey Thigpen
RB Reggie Cobb
FB Joe Perry
TE Troy Drayton
And happily enough, it turns out to be a really fun team to play with. I don't find Brister as repugnant as you do, apparently. He does tend to throw wounded ducks from time to time, but he's got some arm strength, and he actually has some speed. Yesterday I almost converted a 4th-and-17 on a Brister run. I called QB Sneak from the base spread shotgun set while the other team was in a 3-2-6. Drayton and Perry are basically tight ends in that set, so they got good blocks, and Brister ended up THAAAAAT close to crossing the first down marker.
Joe Perry is a beast of a player. His skills are speed burner and cutback, but he's super powerful. The dude can truck through generic linebackers and defensive backs without even charging up. At the same time, he does have speed burner, so you can flex him out in any of the fun Giants formations from 2K5 (twins FB spread, base spread, base bunch, etc.), and if the other team is playing man, he can toast most linebackers that end up on him. In about a week of playing time with this team, he's got 3 40+ yard catches for me. The downside, as befits a 1950s fullback, is that now and then he'll develop hands of stone, just flat dropping the easiest passes. Yesterday he leaked out of the backfield on play action, outran the linebacker who was late finding him in coverage... and dropped a wide open pass in the endzone on 3rd down.
Eric Martin is a little inconsistent, but he's entertaining. His one skill is bump buster, and it seems to make him not only good at beating the jam, but also at run blocking. In that same game where Perry dropped the TD pass yesterday, Martin pancaked both Lem Barney and Willie Brown on run plays.
On defense, pretty much everyone surprised me with how good they were. Millard gets almost as much pressure as Jerome Brown for me (although part of that is probably lining up next to gold Marchetti), and Rulon Jones is great at covering the run and also manages to get some pass rush. I've used Buoniconti before, and he's awesome in pass coverage (which is pretty much all I want my MLB to be doing). And Dick Anderson is really dependable in deep coverage, even though his only applicable skill is clutch. (He's got clutch, loose ball magnet, signal stealer, and wrap up tackler.)
I'd say pretty much the only person I'm not too happy with is Drayton. Maybe I should trade him out for a kicker.
