We keep all five RBs (Williams, THT, Wells, LSH, and Sherman in no particular order) if all look good in training camp. IMO the only locks of the 5 to make the roster are Williams and LSH because Williams is a rookie and LSH brings ST value.
I'm admittedly excited about Williams. He doesn't show that ooh's and aah's speed that you look for, but he's got very good run vision and he runs hard for a smaller back.
IMO those are traits that Beanie lacks, or at least he hasn't shown it so far. Beanie is a physical specimen, but posters saying he's hard to take down are smoking crack, Beanie falls down with the slightest of contact. THT runs hard and is harder to take down than Beanie (he also produces more big plays because he doesn't fall down with shoestring tackles), but his fumbling problems and poor run vision relegate him more to a backup caliber player, and that's assuming his fumbling issues begin to fix themself. If he continues to fumble at the rate he does now, THT will be out of the league in a few years.
We have some talent a RB; If Beanie can learn to stay on his feet better, he has legit homerun potential and has good size and power and Ryan Williams has great run vision and toughness. The problem is, we don't have the offensive line that can consistently punish a defense with the running game. Levi Brown was the worst starting tackle in the NFL last season by most objective (statistical) measures last season. We don't know what we're going to get out of Hadnot or someone else at LG (Hadnot has excelled as a run blocker in the past though). Sendlein is more of a finesse center. Lutui is real up and down; looks very good at times, but is also prone to taking games off. Keith IMO is the best run blocker on the line (and Bridges was very good in relief) but he missed numerous assignments as a passblocker so he's exactly a sure thing.
I do agree with those on the board that continuity is the answer and that a massive overhaul won't fix the line right away and may actually cause it to regress. IMO we look to replace Levi Brown and then resign Sendlein and Lutui. A propose line of Gaither, Hadnot, Sendlein, Lutui, and Keith is a pretty good line moving forward. If we were to sign Gaither, next draft we need to find at least one good line prospect, and start to draft a guy nearly every year.
The lack of quality behind our starting five is alarming and could be devastating with only an injury or two. Bridges is the only guy who has proven that he can be relied upon to start in this league, and as crazy as this sounds, if we don't bring in a LT I would start Bridges at LT over Levi Brown.
Furthermore, if we don't address QB the running game will continue to suck. I read posters on this board act as if we sucked running the ball because of a lack of attempts, but from my eyeball test, I saw a team that was decently effective considering the defensive fronts we faced. Defenses consistently brought seven and eight men into the box, daring Anderson/Hall/Skelton to beat the run blitz with a pass and they consistently failed to find the open man with only a few defenders in coverage.
Few teams can run in those situations, especially teams that aren't run oriented in the first place.
